Problem with 2.6.20 and hostap_cs (Netgear MA401)

[David G Hamblen <dhamblen@adelphia.net>]

I've got the ieee80211 and hostap code compiled as modules for my MA401 
card,  and the system locks up when I insert the card.  No keyboard, no 
sysrq, no logs after reboot, no nothing. The same configuration works 
fine under 2.6.19.

If I first insert my old 3com 3c589 card, then eject it and rmmod the 
3c589_cs module, the insertion of the MA401 works completely. Preloading 
the modules with insmod or modprobe doesn't help.

Was there a change in the pcmcia or networking initialization code 
between 2.6.19 and 2.6.20?

Here are the relevant modules.
