PCI warning on boot

[Stephen Thudium]

During boot the first message after loading the kernel is:

      PCI: Cannot allocate resource region 0 of device 0001:10:18:0
      PCI: Cannot allocate resource region 0 of device 0001:10:19:0

I have a G4 iMac (looks like a lamp). Any thoughts about this "warning"?

Thanks.
