Xorg.0.log

After resume from suspend or hibernate the screen is green with some very wrong
x resolution or blooming with flicker. I ran radedontool regmatch and compared
before and after, and when I manually regset LVDS_GEN_CNTL 0x003c00a5 the
screen comes back and everything is fine.

Latest git of DDX. The Ubuntu 2.6.32-5.6-generic kernel is based on 2.6.32-rc8.
