PCMCIA control bug, not the driver.

The I/O, memory map and (to a limited set) IRQ are decided by the OS, so
these settings are not directly useful.

It's a 21143, the tulip driver is correct.

The PCMCIA control code read the range incorrectly.
This was a known bug with the beta releases of RH 7.2.  Are you certain
that you are using a final release?  (I don't for certain that the bug
was fixed, but it was known well before release.)
