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. Regards, STefan
