Still an issue with recent kernel ?
Yes. The exact same thing is still happening to me on 2.6.38-rc4 and xf86-video-ati git.
As I already mentioned the garbled screen issue goes away when using xrandr after resume. I personally fixed this for me by executing the following *dirty* quirk-script on resume:
export DISPLAY=:0 export XAUTHORITY="/home/$USER/.Xauthority" xrandr --output DVI-0 --mode 1920x1080 xrandr --output DVI-0 --mode 1680x1050
But obviously this cannot be a permanent solution.
