Some BIOSen somehow end up with the jmicron port in use but the PCI device
disabled again after the firmware enabled it.

This patch isn't relevant to the upstream plans as upstream will get a 
specific Jmicron pata driver in 2.6.19. Basically if its a Jmicron we enable
it and probe it anyway, that will do the right thing in all the cases I've
tested. Change is intentionally minimal.
