PCI LKM support has been in -current for quite some time (I 
think I added it one year ago), but I temporarily removed it, 
when I completely rewrote the PCI code.

If you need it, it is easy to put back. The API was that the
PCI LKM just called 

	pci_register_lkm(struct pci_device *p, int rev)

with the parameter of the DATA_SET and rev=0.

The rescan was automatically performed from within that LKM 
registration function.

Sorry, I'm in a hurry, now. If there is any need for PCI LKM
support, I may be able to put back that feature over the weekend.

I also prepared a simple shell script that could be run from
/etc/rc and which searched for PCI devices that had no driver
compiled in, and tried to modload the corresponding driver
(actually used for one ATM card driver, so far).

Check the -hackers mail archive about one year back for some
more information, the announcement and some discussion on the
topic of PCI LKMs.
