Of course. This is why i will invent that evil "first post the card, then
restart userpace" in s2ram. To finally get that world domination. ;-)

I do not claim they are perfect, but at least i am not doing
"lspci|grep ATI|cut -d..."-like stuff to find the graphics card anymore ;-)

I would just move the hook from 20video to 99video. It does not really make
a difference if you save the vbe state before or after unloading modules
AFAICT (s2ram actually saves it _very_ close to the actual suspend and
restores it as soon as possible, and i have not seen any negative side
effects of that).
And with radeontool and stuff, the later you turn off the light, the better
(in case something goes wrong, the user has a chance to see something).
