regression: Xorg get 100% cpu and freeze

I use CURRENT from 2011-11-18 - all OK
After update to today - I have problem - on start, Xorg get 100% CPU and 
freeze (monitor go to turn off)
I recompile Xorg, all modules - no happy.
I try update x11-drivers/xf86-video-ati to 6.14.3 - no happy

If I delete /boot/kernel/drm.ko - all work OK, but very slow...
