Hmm, well another common issue relating to hangs when doing suspend/resume is bug #138256. To see if you're seeing an instance of that, could you try adding this to your xorg.conf?
Section "Device" ... Option "ForceEnablePipeA" "true" EndSection
If it does, then please give the laptop's model name and number, and the output of `lspci -vvnn | grep -A1 "VGA compat"` and I can add a quirk for it.
