Not a kernel issue; maybe timing?

Ok, I'm a little confused about exactly what worked and what does not
work.  It sounds like the 3c589 card worked on this box with [some
earlier driver version].  I'd like to see the kernel messages from
that case.  And both cards work on another box, but you don't really
say how that box is different from the one that doesn't work.

As for the potential for an IO overlap, you cannot tell much by
looking at /proc.  Those files show what resources Linux knows are in
use.  But you can have a conflict with a device Linux doesn't know
about.  Excluding resources in /etc/pcmcia/config.opts is an easy
thing to try.  I suspect it won't help, but you should try.

I don't believe that changing kernels is likely to make any difference
at all.

Another thing to try is to load the pcmcia_core module with an option
like "io_speed=300" to change the timing of IO accesses.

Clarification

To clarify what does and doesn't work:

With an older kernel and pcmcia-cs, 3c589 was functioning on my 'new' hardware. With 2.2.12 and pcmcia-cs 3.1.10, 3c589 does not work. The Aironet driver that worked on all kernel/pcmcia versions on my 'old' hardware has not worked yet on the 'new' hardware, regardless of software versions.

I've tried excluding, no luck.

I just tested pcmcia_core with different io_speed parameters, including 300, no help.

I'm going to revert back to something that does work on my new hardware - an older kernel and pcmcia-cs. Then, I'll move up from there, and hopefully identify if it is the different kernel version, or pcmcia-cs version that is making the difference.
