I remember similar thing with i810 video on x86 - with 24-bit depth I had only indirect rendering (because of lacking video RAM), while with 16 I had direct rendering.

In debian or ubuntu i would apt-get source the package, apply the patch, then recompile and reinstall. Can someone point me to resource that can help.
