does your video resume after a suspend to ram with kernel-2.6.15-1.1823_FC4

[Paul Johnson]

Which part do you refer to in "current setup in rawhide"?  You mean
g-p-m?  If so, I think that means g-p-m is relying on VBEtool, and 
that's probably causing the corruption I experinece.  If X is running
when a VBE suspend is used, then upon restore, the video turns back
on, but the display is just a blurred gradient, and I don't think the
system is responding to the keyboard at all. The caps lock light does
not go on or off in rsponse to the key.

In contrast, if I suspend to RAM with ACPI alone (my script is pasted
in here), then when the system resumes, the video stays dark, but it
does respond to the keyboard.

Thanks in advance
