I compiled Mesa CVS and after installation - my acceleration was broken, so I enabled LIBGL_DEBUG and found that Mesa search for r300_dri.so not in /usr/xorg/lib/modules/dri, but in /usr/X11R6/lib/modules/dri. I made a symlink and now it works correctly.

I never had such problem before, is it a new change?
My distribution uses /usr/xorg/lib/modules only.
Is /usr/X11R6/lib/modules proper way now?
