I tried this and it didn't work. I've also found out why. It's because the dri 
part of fglrx crashes after resume.

fglrx and suspend works fine if I disable DRI in xorg.conf. With dri enabled 
I've found no way to resume a started X session :-(

I suppose that vbestate doesn't touch the radeon specific settings set by 
fglrx and fglrx doesn't restore them carefully enought. If I start a secound 
X server after S3 I can't revive the original session too because the 2nd 
server doesn't initialize dri.

I've written a bug report to ATI yesterday and I'm waiting for a reply.
