it wasn't auto-detecting, so i tried setting it manually. made no difference.

with kernel pcmcia, it detects the Ricoh RL5c475. but none of the drivers
which *should* work (linux-wlan-ng, hostap, orinoco) will detect the senao
wireless card...which is why i tried pcmcia-cs instead.

i'll try this.

no SMP, but will try disabling IO-APIC next time i recompile the kernel.

maybe i should just get another pcmcia adaptor. what's recommended
