Question Partial card functionality, memory port probs?

And: swlr# cat /proc/bus/pccard/memory 000d0000-000d0fff : card services

With that out of the way, I have an interesting problem with
multiple cards.  The hardware is an embedded system board with an onboard PCMCIA controller.  The processor is an AMD Elan
SC400 (http://www.amd.com/products/lpd/elan400/21026b.html) that has PCMCIA functionality 'built-in'.  I've had
3c589_cs working on older kernel versions and older pcmcia-cs
 versions, but with my existing software, I have a problem
 running 3c589_cs, and more specifically Elmer Joandi's
 Aironet 4800 driver.  I have never been able to make the
 Aironet 4800 card work on this hardware, no matter what
 software versions I've used.  With both cards/drivers, the
 card is found, but the driver has a problem doing anything
 with it.  I can configure it with an address, and try
 pinging, but I get errors, such as these with 3c589:

eth1: 3Com 3c589, io 0x310, irq 3, hw_addr FF:FF:FF:F9:FF:FA
  32K FIFO split 3:5 Rx:Tx, auto xcvr
eth1: interrupt(s) dropped!
eth1: interrupt(s) dropped!
eth1: interrupt(s) dropped!
eth1: interrupt(s) dropped!
eth1: command 0x5800 did not complete!
eth1: command 0x5800 did not complete!
eth1: command 0x5800 did not complete!
eth1: interrupt(s) dropped!

.... and so on. Note the hw_addr - probably bad! This is the same thing that happens with the 4800 card, I get a bogus MAC address, and various error messages when I try to read/write to it.

Pulling the card I'm using and trying to load the drivers produces the logical response - card not found. I tried loading X driver for Y card to see if that was a problem/possibility, and that produced the logical response as well - wrong driver for the card. It seems that the cards are being seen and identified, and I can "kind of" communicate with them, but not all the way.

Memory addresses 0xd0000-0xdffff are shown free by the system, and the probe, and I have verified vigorously with the hardware manufacturer that this is the case.

Anyone have any ideas?
