If the device ids are in the driver for this device, are you sure the
driver is loaded?

What driver should be controlling it?

This doesn't look like your PCI devices above, as the pci device bus
numbers don't match.

Can you provide the output of:
	lspci -n
	lspci
	lspci -k
for us?

as well as the full boot log?

thanks,
