Because, in my case (RV770), 'low' mode freeze my system. I want to know if there is a real difference between 'low' and 'mid'.
default engine clock: 850000 kHz
current engine clock: 800000 kHz
default memory clock: 975000 kHz
current memory clock: 975000 kHz
voltage: 1313 mV
low profile:
default engine clock: 850000 kHz
current engine clock: 500000 kHz
default memory clock: 975000 kHz
current memory clock: 975000 kHz
voltage: 923 mV
but remember that my chip is RV790

You will need to compile the driver from scratch for 32 bits. This is an ugly process in gentoo. A friendly user here posted a rough way to do it, so I'll share it with you. You might have to update a few things (my builds are in /usr/local/portage). Don't do this unless you understand what you're doing, though!
Code:cd /usr/local/portage//x11-libs/libdrm ebuild libdrm-9999.ebuild unpack cd /var/tmp/portage/x11-libs/libdrm-9999/work/libdrm-9999 export CFLAGS="-m32" export CXXFLAGS="-m32" sh autogen.sh --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib32 --libdir=/usr/lib32 --disable-dependency-tracking --enable-shared --disable-static --disable-dependency-tracking --enable-udev --disable-intel --disable-nouveau-experimental-api --enable-radeon --disable-vmwgfx-experimental-api --enable-libkms make cp .libs/libdrm.so.2.4.0 /usr/lib32/ cp ./libkms/.libs/libkms.so.1.0.0 /usr/lib32/ cp ./radeon/.libs/libdrm_radeon.so.1.0.0 /usr/lib32/ cd /usr/local/portage/media-libs/mesa/ ebuild mesa-9999.ebuild unpack cd /var/tmp/portage/media-libs/mesa-9999/work/Mesa-9999 ./autogen.sh --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib32 --libdir=/usr/lib32 --disable-option-checking --with-driver=dri --disable-glut --without-demos --enable-xcb --disable-debug --disable-glw --disable-motif --enable-glx-tls --enable-asm --with-dri-drivers=,swrast,r600 --enable-gallium --with-state-trackers=glx,dri,egl,vega --disable-gallium-llvm --disable-gles1 --disable-gles2 --disable-gles-overlay --disable-gallium-svga --disable-gallium-nouveau --disable-gallium-i915 --disable-gallium-i965 --disable-gallium-radeon --disable-gallium-r600 --disable-gallium-i915 --disable-gallium-i965 --disable-gallium-radeon --enable-gallium-r600 --enable-32-bit --enable-texture-float make cp lib32/libGL.so.1.2 /usr/lib32 cp lib32/libGL.so.1.2 /usr/lib32/opengl/xorg-x11/lib/ cp lib32/libGLU.so.1.3.071100 /usr/lib32/ cp lib32/libEGL.so.1.0 /usr/lib32/ cp lib32/libOpenVG.so.1.0.0 /usr/lib32/ cp lib32/egl/* /usr/lib32/egl/ cp lib32/r600_dri.so /usr/lib32/mesa/r600_dri.so cp lib32/gallium/r600_dri.so /usr/lib32/mesa/r600g_dri.so cp lib32/gallium/swrastg_dri.so /usr/lib32/mesa/ cp lib32/swrast_dri.so /usr/lib32/mesa/ rm /usr/lib32/dri/r600g_dri.so rm /usr/lib32/dri/r600_dri.so ln -s /usr/lib32/mesa/r600g_dri.so /usr/lib32/dri/r600g_dri.so ln -s /usr/lib32/mesa/r600g_dri.so /usr/lib32/dri/r600_dri.so

So I conclude there must still be something missing in the radeon code somewhere (further: s3tc is WIP in the status matrix). That's why I asked how much is still missing.

you need to compile mesa + s3tc for 32 bit. thats really tricky especially for r300g which wants llvm by default. when you use kanotix or pure debian you could try my scripts. i do not support ubuntu, there just use a ppa. the simple instructions to compile mesa are only for 32 bit or when you use only 64 bit apps with a 64 bit os. compiling 32 bit libs on a 64 bit system is much more tricky as you have to fullfill the depends of course there too. for wine you need of course 32 bit libs.

But you need the 2.6.39 kernel.
I use mesa, xf86-video-ati, libdrm from git, kernel 2.6.39.1, libtxc_dxtn 1.0.1, printenv says R600_ENABLE_S3TC=1, glxinfo says GL_S3_s3tc, GL_EXT_texture_compression_s3tc and OpenGL renderer string: Gallium 0.4 on AMD RV710 and the following files are present:
/usr/include/txc_dxtn.h
/usr/lib32/libtxc_dxtn.so
/usr/lib64/libtxc_dxtn.so
Is this all I have to do?
Because no single wine game works with s3tc, though everything seems to be ok. (wine is from git and seems to support S3tc since 2004)
In those games which don't check for S3tc I have severe graphical glitches and those which check tell me "texture compression support not detected".
These games are 32bit Windows binaries, but I don't get it why they don't work...

Can someone tell me, how much there is left for full S3TC support in r600g? Every time it's needed, I have to switch from my pc to my laptop which uses intel graphics (not fast at all, but at least they show me a non-scrambled picture ^^).
(Yes, I installed libtxc_dxtn, but r600g doesn't seem to be able to use it completely)
It's my daily routine to check mesa for new patches regarding this topic :-)
