You don't say.

Well, we just don't know how to tell the firmware what the keys are.

Well apparently the Lucent cards are also HFA384x.  I'm pretty sure
this is a firmware issue.

It certainly doesn't work with wvlan_cs.o.  Last I knew I didn't think
it worked with linux-wlan either, but I should check if that has been
added in a recent version.

Mark S. Matthews of Absolute Value Systems signed the NDA,
linux-wlan-ng is written based on that information.  orinoco_cs is
based on reading the code from wvlan_cs (derived from Lucent's
published cut-down code, HCF-Light), the AbsoVal driver, and the
BSD if_wi driver (based on both HCF-Light and reverse engineering, I

That would be nice.  I believe SoftICE can do that, but it is not
free (in fact very expensive).
