Sounds like the problem I had with my LCD.  It was the refresh rate the
hibernation made my LCD attempt to display.  I used to get the "bloom"
effect way back when I started using Ubuntu and installed Dapper/Edgy on
this laptop.  I finally figured out X was not initializing the display
properly, once I set proper refresh rates in my xorg.conf the problem
went away.

It recently resurfaced with Gutsy when I used uswsusp's s2disk utility
to hibernate the machine.  Now with Hardy this laptop no longer
hibernates at all so my problem has been (*ahem*) fixed.

So is it during the usplash display of the Ubuntu logo and the progress
bar? Or is it during a text-mode display?  I don't know of any way you
could fix this problem however.  When I asked here about my (possibly)
similar problem the list had no advice - uswsusp does not allow me to
customize those refresh rates so I was SOL.  I doubt pm-utils will let
you set the rate too.
