This has nothing to do with the source code and everything to
do with the hardware.
All 802.11b cards supported under Linux are :
o 16 bits
o PIO (no shared memory, no bus master)
o use somewhat bloated host<->hw communication

So, it's not like you have a choice...
Host based WEP adds some overhead, if you don't like that get
yourself an up-to-date firmware so that you can offload WEP.
