Yup, but it just tries the code that works for 2.4.x on my box, and when
it fails, tries the 2.6.x-based path. So it's blindly trying to open the
/proc/bus/pci/* stuff directly instead of "selecting" the right one for
the kernel. I'm not sure if there's any architectures where a PCI domain
tree and a non-domain tree are exported. If there is, and there's a video
card in both, then it probably won't do the right thing.
As far as I can tell, though, there doesn't seem to be such hardware...

I haven't tested this against any other architectures, as only my Ultra 5
currently has a video card that's under the PCI device tree.
