I use ndiswrapper and I don't see that problem.

I think this is because of the entry for ipw2100 in the
/etc/modprobe.conf file. It loads the modules regardless of whether you
set onboot or not.

YOu might want to take a look at the attached script. (got it from the
web. The author's name and email is in it)

He's just detecting what networks there are and then loading it up.
(through profiles but personally, I don't use profiles... so...)

What I can suggest is that you hack this init script to load ipw2100
urself and not depend on modprobe. That way, You have control.
