Hm. Someone other than a Linux-ruby user finally complaining. :-)
Try patching XFree or XOrg with the proper patch

http://www.ltn.lv/~aivils/files/080_pci_isolate_device_feature.diff

for XFree, or

http://www.ltn.lv/~aivils/files/Xorg-6.7.0-isolate_device.patch

for XOrg, it's applicable for XOrg-6.8.x, too.

Then add
          Option         "SingleCard" "on"
to your Section "ServerLayout".
