Card dropped dead during normal use after several days of 
operation, 2.6.27.4 kernel with compat-wireless-2008-11-17.

Removing/reloading module didn't restore the card.

Toggling rfkill switch also didn't have any effect.

Had to power off the system to get the card to come back.

IBM T61 laptop, no other kernel logs, system had been suspended/resumed
to ram multiple times but not w/in 5 hours of the bug happening, first
time this has happened on my system however a friend with the same
hardware has seen it continually for several months under high load
situations (no logs on that one, so anecdotal.)  Not aware of any high
loads on my system when it triggered, however.
