This will likely fix your panic, but I think the card is likely to still not
work:

John,
You are right, the panic has got away, but
the card doesn't seem to work. After
issuing "ifconfig wlan0 up scan" I just
get lots of
ral0: could not read from BBP
ral0: timeout waiting for BBP
messages on the console.
Shall I give up on this particular device?
many thanks
anton
