    Same thing with 2.6.32-rc6-git1 and 2.6.31.y with drm-next (as per the RadeonBuildHowto) (even after rebuilding world in gentoo - just in case :-D).

    Kernel panic at boot with next-20091104 so couldnt test...

      Here's a low quality picture taken from my phone:

      Note that this screen is static, it doesn't change if I move the mouse and I can't switch to a console.

      Do you think my linker options could be breaking something? I use -Wl, --as-needed

      CFLAGS are sane though (-O2, pipe, -fomit-frame-pointer, -march=amdfam10h)

        Update: It seems X works when KMS is NOT enabled after all... As I said, with radeon.modeset=0 running X in a shell results in a black screen (with no cursor and the backlight going eventually off) but when I start the xdm init script (configured to start kdm) it works fine when KMS is disabled.

        Everything seems to work fine including kwin's effects.

        I'm starting to believe that what I'm experiencing might be similar to this bug, but unfortunately I don't have the tools or knowledge to further investigate: https://bugs.freedesktop.org/show_bug.cgi?id=24218

            yeap it's fixed... thanks a ton!!

            3d seems a little snappier than no KMS and dri1, albeit one can find a few transparency artifacts on the plasma desktop...
