Public bug reported:

Binary package hint: xorg

The screen corruption is evidenced in both framebuffer (console) and X
modes under KMS but not UMS.  I didn't try KMS in Ubuntu 9.10.
/var/log/kern.log and /var/log/syslog show a conflict during boot
between radeondrmfb and the generic EFI VGA and that is when I see the
corruption commence.  Screenshots don't show any problem.  I am
attaching a digital photo of the screen which shows what looks to be a
pixel re-ordering problem.  This appeared when I upgraded from Ubuntu
9.10 to Lucid Lynx and remained after I enabled the xorg-edgers PPA.
