I think that the SEEPROM reading might be very timing
dependant... David? I'm worried that whatever the path in the chipset
is that generates the byte enables might be too slow. By trying I/O
space, I'm just trying to take a different path through the chipset.

Get a newer revision of the firmware, which you cannot do on a box as
old as yours :-(

Try the appended patch & see if it helps. If it does and if David
approves, I could clean it up & make it get a mask of devices via a
getenv like the Qlogic driver does.
Cheers,
