In principle. OTOH, the X server insists on examining the PCI config
regardless of the fbdev interface having everything set up OK. And the
fbdev driver currently does not provide a method to report the IO base for
the chipset registers. Neither does it provide a way for the X server to
associate a PCI device with a given framebuffer device to figure the
missing information from the PCI resources. You might argue that the X
server could reconstruct that association from the PCI resources and the
fb_info video mem address. Using the PCI resources for all purposes is
probably easier though.

I've not seen fbdev_open_pci called (on the Mach64 driver, that is).

Care to post a lspci -vv log?
