8139-based Airlink ASOHORL PCI network card not working under 2.6?

I'm using Ubuntu 5.10 (x86) and just popped in a cheap Airlink ASOHORL
10/100 PCI network card, which I bought because it was something like
$5 and promised Linux compatibility on the box. The card is based on
the RTL-8139C chipset (according to rtl8139-diag). However, when I add
the card to /etc/network/interfaces and try to ifup it, I get these
errors:

SIOCSIFADDR: No such device
eth2: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
eth2: ERROR while getting interface flags: No such device
Failed to bring up eth2.

(Yes, it's the third network card in this box.) I looked at the driver
diskette and they provide drivers for 2.2.x and 2.4.x, but not 2.6.x
(I'm running 2.6.12-10-386). Foo.

Using the 8139too module with debugging turned on says this:

8139too Fast Ethernet driver 0.9.27
ACPI: PCI Interrupt 0000:00:0c.0[A] -> Link [LNKA] -> GSI 10 (level,
low) -> IRQ 10

and I likewise get errors from 8139cp.

lspci -vv -n says this:

I glanced at the source for the 8139too driver and I see 10ec:8139
listed there, so I'd think this would work, but clearly it doesn't. I
suspect the root cause is that it can't reserve the I/O region, and
that this isn't really 8139-driver-specific -- I just don't have a good
idea how to go about fixing that. Any suggestions?

Agreed. If you look at /proc/ioports, you should see what
has beaten the driver to that region.
