Does it work fine if your xorg.conf only has this, thus only limiting the virtual display size?

Section "Screen"
 Identifier "laptop_screen"
 SubSection "Display"
  Virtual 1024 768
 EndSubSection
EndSection

I would still consider this to be a bug, but it is being improved in the newest drivers with the use of a memory manager which can distribute the video RAM in a more flexible way.
