Yes, most likely you can just remove that entry. This might be entries
for PCI slots though, so a problem might only occur when you plug in a

might work, might not. This depends of many things for example on how
the mainboard is wired.

yes, | is OR.
You should change the device position.
NOTE: 0:16.0 might be 0x16 or 16 (0x10) - you need to find to make it
work right. lspci shows hex values - this confused me quite some time
when we did the opteron port..
Not necessarily the device ID though, since Linux might not support the
actually used interrupt router. I think on K8 boards the IRQ router
device and vendor id is still set to the k7 interrupt router (it was in
the past) because the two devices were compatible and linux did only know
the older part.
