| I was playing with some stuff to muck with the video card on the sun5
| I have.
|
| dmesg shows;
| pci2: <display, VGA> at device 2.0 (no driver attached)
I did a boot -v, and I think it shows the actual problem...
PCI_* stuff is returning the physical bus number in the PCI selector,
but, actually uses the logical bus number when trying to access the
devices.
I'm not sure which is correct scenario, whether it should return the
logical bus in the selector, or whether it should use physical bus when
looking up the device.
