So far it looks that this set of updates killed my X quite
thoroughly. An attempt to start it end up with a dead screen and
stopping X does not help. Only a reboot forces re-initialization of
a screen by BIOS. A keyboard is still operational as I can reboot
from it "in blind".
In logs I see at the bottom:
(II) RADEON(0): [drm] register handle = 0xfce00000
(II) RADEON(0): [dri] Visual configs initialized
Backtrace:
and that is all. Backing off the previous version of xorg-x11-drv-ati
does not help.
Oh, I see, already reported.

Just added some hints how to avoid that bug.
