I think what's happening is that Karmic and Lucid have implemented new
(but different) sets of scripts which control whether and how the quirks
are applied.  In Karmic it was possible to prevent the quirks from being
disabled by editing /usr/lib/pm-utils/sleep.d/98smart-kernel-video to
comment out the call to remove_all_video_quirks.  That hack got
suspend/resume working for me on at least one machine (including a Dell
laptop with NVIDIA graphics).

In Lucid the scripts have been changed again in an attempt to make them
more intelligent so the video suspend/resume will work on more hardware.
But it continues to fail on the ATI X1100.  If you study the scripts you
should be able to figure out how the hack them to allow the quirks to
run, and there's a good chance that will cure the problem.  But I
haven't tested it.

I frankly don't understand why this kind of problem has been allowed to
persist for so long.  It seems to me that if the user manually enables
quirks by creating or editing the .fdi file then the script should not
thwart his efforts by disabling the quirks.  But the devs seem to
disagree.
