Hi Dave & Mike,
Thank you for your answers. Dave: you're right. The pcmcia module is
actually required for the wifi module.
Even after I commented the pcmcia line in the /etc/modules out, it
still gets loaded as pcmcia is used by cfio
and cfio is used by the mcf25 (wireless driver). So, from a SW
perspective (without knowing anything about HW)
the wireless driver cannot do without pcmcia. As for the shared vs.
exclusive interrupts, what I can tell you is
that it depends on the interrupt handlers, so that may not necessarily
be an issue as long as each handler "plays nice".
I'm in the process of getting an RMA for this part, so I'll keep all
posted on how it goes.
