I'd take credit, but about the same code was in orinoco.c until it
disappeared in version 0.09.  I've just been adding it back in for
my own use, but getting emails from others about the problem.  So
I decided I'd post it for others.

See above.  I believe it was maybe "borrowed" straight from pcmcia-cs
spectrum24t driver, who have access to the Symbol "Non-Disclosure"
firmware/hardware information. The maintainer of
http://sf.net/projects/spectrum24 would probably be a good place to
find that information.

Super!  No more patching, I'm lazy you know. ;)

Since you don't have a card of this type, I can test any new reset code
with my cards and report back.
