Unfortunately, no. It is actually worse, since Xorg is broken after resume (the
mouse cursor displays fine, but the windows are corrupted ( something like the
lines are interleaved)

my relevant xorg bits, just in case:
Section "Device"
        Identifier      "ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]"
        Driver          "ati"
        BusID           "PCI:1:0:0"
        Option          "GARTSize" "64"
        Option          "XAANoOffscreenPixmaps" "true"
        Option          "AGPMode" "4"
        Option          "EnablePageFlip" "true"
        Option          "DynamicClocks" "true"
EndSection
