That will be very difficult to do then.... The work I did for accessing PCI config registers had to be merged into the tree...

Short of modifing the function in real time to point to your code, I don't have any suggestions... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not." _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
