If you are calling pci_disable_device at all in the fb driver or DRI
driver it is wrong, always wrong, always will be wrong for the main
head. The video device is almost unique in that when you unload all
the video drivers vgacon still owns and is using it. On some devices
that needs PCI master enabled because of internal magic (like 
rendering text modes from the bios via SMM traps)
