Bad mojo.

Can you reproduce the failure of the driver or lspci when you
boot the kernel with "pci=nommconf" (assuming CONFIG_PCI_MMCONFIG is
set in your .config) or "pci=conf1" (if CONFIG_PCI_DIRECT is instead).

The (gzipped) content of your .config.

Kasper, could you check if you have the same symptoms with
2.6.26-rc8 (once your rendering is finished of course) ?
