The wifi card is Cabletron Entersys Roamabout and the driver is an orinoco
driver that comes with vanilla kernel. Here is what lsmod says:

orinoco_cs 14340 1
orinoco 38932 1 orinoco_cs
hermes 6784 2 orinoco_cs,orinoco
pcmcia 32176 5 orinoco_cs
firmware_class 8448 1 pcmcia
yenta_socket 24204 6
rsrc_nonstatic 11776 1 yenta_socket
pcmcia_core 35616 4 orinoco_cs,pcmcia,yenta_socket,rsrc_nonstatic

And these are the relevant syslog lines:

orinoco 0.15 (David Gibson <hermes@xxxxxxxxxxxxxxxxxxxxx>, Pavel Roskin
<proski@xxxxxxx>, et al)
orinoco_cs 0.15 (David Gibson <hermes@xxxxxxxxxxxxxxxxxxxxx>, Pavel Roskin
