Can't get 3D HW working with KMS enabled

Also make sure you compiled the ddx (xf86-video-ati) with kms support.

  prefix:              /usr
        exec_prefix:         ${prefix}
        libdir:              ${exec_prefix}/lib
        includedir:          ${prefix}/include

        Kernel modesetting:  yes

That should do the trick and I did that right from the beginning. What strikes me as odd is the fact that I know my hardware should do it. Back in April when jglisse released his first repo and compiling instruction, I had it working, albeit rather unstable.

Addendum: The kernel I am using is an experimental kernel:

http://wiki.mandriva.com/en/Docs/Howto/Mandriva_Kernels#kernel-tmb

2.6.31.6-tmb-laptop-7mdv

However, maybe it's this:

grep -i kms /boot/config-2.6.31.6-tmb-laptop-7mdv
CONFIG_DRM_KMS_HELPER=m
CONFIG_DRM_I915_KMS=y
CONFIG_DRM_NOUVEAU_KMS=y
# CONFIG_DRM_RADEON_KMS is not set

I created a new initrd with radeon preoloaded and that probably should be just as good, because KMS actually worked as can be seen in the HiRes Framebuffer console and fast switching between X and console.

Check your dmesg to see if you are actually using kms.
