Actually, I can do better than that... except that I can't figure out
exactly which hooks in the driver duplicate the effect of
	ifconfig wi0 down; ifconfig wi0 up

But I would think the right thing to do would be to reset the card as
soon as a command times out... it's *always* a card failure, so far as I
can tell.

I have support for this; Intersil told me that I may need newer firmware
to use ad-hoc mode.

I tried to do this, but screwed it up in some way.  I may try again
later.
