That's what keeps puzzling me: "lshal | grep quirk" shows no results - so g-p-m should go down to suspend (using hal) without quirks and therefore just like "pm-suspend" without any arguments. However, it shows a scrambled VESA-buffer-window just as I get it when using "pm-suspend --quirk-vbe-post". This is why I suspected g-p-m and not HAL, even though it is the obvious culprit for this kind of hangup.
