    Heh, this driver also tries to cache the single PCI register per-channel
    like hpt366.c... This buglet concerns using fast PIO timings and is probably
    harmless though but needs to be fixed -- I'll send a patch soon...
    I wonder what is otherwise wrong with using 2 channels concurrently?
