I guess it has something to do with these lines (taken from 3c509.c in
2.1.115):
/* Reset the ISA PnP mechanism on 3c509b. */
outb(0x02, 0x279); /* Select PnP config control
register. */
outb(0x02, 0xA79); /* Return to WaitForKey state. */
The 3c509 driver is doing it's own PnP detection ... maybe it doesn't work
with the kernel-pnp patches?
