I'd guess this is more likely in the usb side of things, having had
series of truble with usb2 devices under a variety of operating
systems.

I am currently writing this over my wireless ral driver - it turned
out the problem was with WEP. When I turned it off in the AP and ran
ifconfig, it came to life. It has been working now for more than half
an hour. I will investigate the WEP setup later - if I find some time
(I realize it is not recommended and I might abandon it and try the
recent WPA commits).

This was my first attempt at WiFi under NetBSD; it turned out the
query was noise here, more appropriate for netbsd-help; it is on
-current, anyway. The question of the panic when disconnecting the
card remains.
