[MLB-WIRELESS] Richoh RL5c475 and IRQ

i can't seem to get pcmcia-cs to recognise which IRQ my Ricoh RL5c475 is on.

any clues would be appreciated...


system is an athlon 2000, Gigabyte 7VA m/b, with 1GB RAM, running debian
unstable.  kernel is 2.4.21.  pcmcia-cs version is 3.2.2.  hostap version is
latest from CVS.

the card is a Veritech VAC2511-D (rebadged Senao).


running "/etc/init.d/pcmcia start" shows this:

"no pci irq".  not good.  so, of course, hostap_cs can't talk to the card:
