This sounds at least somewhat like the problem and solution described here:
(you'll need to read from bottom up)
http://lists.pcxperience.com/pipermail/linuxr3000/2005-February/001417.html
Its the same wireless card (or at least driver) and OS, but different
laptop.  It doesn't mention kernel panics, but problems going between
WEP and open nets.  A summary of the solution seems to be to issue:
iwconfig wlan0 key off
when going between the encrypted and open nets.  This may be
unrelated, but it's at least worth a shot.

Hmmm, does appear to help so far.  I issued key off right after modprobe
ndiswrapper and it hasn't crashed yet, thought the "Wireless event too
big" does appear in logs still.  Can't connect, but that was expected -
the signal is really low.  The fact that mine panics and theirs doesn't
could be the difference between Fedora Core 2 and Fedora Core 3.  It
would be nice to know if this is a kernel problem or an ndiswrapper
problem, so I know who to report the bug to.  Any ideas?

Cheers,
David
