Hi Greg.

On an older Intel 430VX system, 2.6.20.4 complains a bit:

===
usbcore: registered new interface driver usbfs
usbcore: registered new interface driver hub
usbcore: registered new device driver usb
PCI: Probing PCI hardware
PCI: Probing PCI hardware (bus 00)
0000:00:07.1: cannot adjust BAR0 (not I/O)

0000:00:07.1: cannot adjust BAR2 (not I/O)
0000:00:07.1: cannot adjust BAR3 (not I/O)
Boot video device is 0000:00:08.0
pnp: the driver 'system' has been registered
pnp: match found with the PnP device '00:07' and the driver 'system'
NET: Registered protocol family 2

00:07.1 is IDE (lspci -s 7.1 -vv attached, due to wrap). It's no doubt safe to ignore but looks a bit alarming...
