These message about unknown devices means that the Linux kernel has
found devices that it didn't know about (yet). In
/usr/src/linux/pci/pci.c is a table of PCI devices currently known to
Linux. If you have a relativly new (or some kind of exotic) hardware
Linux can't find the PCI id in this table and issue a warning message.
You usually can ignore it but you will get problems if this devices
cannot be used because of being unknown. For example, if you have a
really new PCI SCSI adapter which is unknown to Linux you probably
will be unable to access it.
