The following patch (in sys/net80211) makes a Lucent Gold card be able
interwork in both IBSS and ad-hoc demo mode with an identical card in
a 1.6-stable system.

I now realize (thanks to Sam and David for pointing this out to me,
offlist) that this change is in general incorrect, because other
non-Lucent, or perhaps non-PRISM cards require the use of a node table
in IBSS mode.  But I post it in case any -current users depend on IBSS
or ad-hoc demo mode with Lucent cards - I had to boot an old kernel to
be on the net until I made the change.
