I've got a t41 with a Cisco MPI350 Card. I'm currently running
FC2test2 (plus rawhide) and 2.6.4 kernel. 

The MPI350 is a very, very tricky beast. Using the RHEL 3 kernel and
the mpi350 module (from airo-linux.sourceforge.net) I am able to use
WEP and the MPI350 with no issues. 

The newer unified airo/mpi350 driver, however, doesn't work with
WEP. This is the case both in 2.4.2x and 2.6.x. I *AM* able to use the ACU
to confiure the card, though. It just doesn't talk properly to the
network if WEP (64-bit or 128-bit) is enabled.  

The cisco airo PCMCIA card works just fine.

Well, I don't use WEP at home, so no. But I think it's do-able. using
the right kernel/driver/firmware combination. First things first ;

1) make sure you ahve the 5.00.03 firmware for the MPI350 - and not
   anything newer. The newer firmware doesn't play nice with Linux.
2) Make sure you use the mpi350 kernel module, and not the unified
   airo/mpi350 airo module
3) run the acu as root. It doesn't let you configure everything as a
   "normal" user. 

Do you ahve something more exact than "doesn't work" - what are the
symptoms?
