I rebuilt ifconfig from the sources you checked in, although I didn't do
a full buildworld.  Does it depend on a library change somewhere?

The key I got from wicontrol wasn't zero-padded.  It showed all 26 hex
characters.

Ahh.  I take it there's no way for the driver/card to autodetect that
there's a turbo network around and attach to it?  (The Windows driver seems
to find it..)

Yeah, I know.  I need to see if I can get an IPSec tunnel running to the
router.  My guess is that it will probably only want to talk IPSec over
its "internet port".
