You need to patch your driver to include this patch:

http://ipw2100.sourceforge.net/patches/ipw2100-0.62-all_patches.patch

It says 0.62 but applies cleanly to 1.0.0. I still can't get it to work 
reliably--I lose the connection shortly before the connection rekeys (I use 
WPA-EAP) and then it comes back after the key negotiation completes.
