Well, on my laptop iwconfig definitly still shows "wireless". I'm assuming
here that iwconfig reads the actual value from the card and not what it was
last set to.

Ok, so that would explain why the 486 works. Actually, without iwconfig I
can't even set the 486 to ad-hoc mode or set the frequency. The default IIRC
is managed mode so it's suprising it works at all (though maybe wvlan_cs is
different, never used it before). No, I have not done anything with module
options either, cardmgr is defaulting to insmod :(.

When I get home tonight I will see if I can reproduce the behaviour between
my laptop & desktop.

BTW, have you considered adding iwconfig mode ad-hoc-ibss and iwconfig mode
ad-hoc-demo? And have the iwconfig output display which it is using? I was
looking at adding it but there doesn't seem to be a consistant interface
between cards.

I also have a small patch that adds /etc/ethers support to iwspy.
