Oh? I thought that was the point of wpa_supplicant? To do things in
software that the hardware can't do..? So it wouldn't matter what the
hardware driver natively supports. Or, do I have the wrong end of the
stick here?

OK, how might I find out these details? I presume some poking in proc?
I note it doesn't appear in lspci, though I understand that's normal for
PCMCIA cards.

The following I guess:

orinoco_cs             15556  1 
orinoco                34388  1 orinoco_cs
hermes                  7200  2 orinoco_cs,orinoco
pcmcia                 33788  1 orinoco_cs

OK.. I'll build myself another kernel with hostap in there as well, and
try that out. Thanks for the suggestion
