Ah, OK.  I believe we're setting EUMBBAR, but probably just to the
location that was used by DINK32, so if that's different, there may
well be some niggles there.  And, yes, we don't make use of the DUART
on the chip since that's not present on the other PMCs.  It should be an
option, but I haven't actually had a chance to play with an 8241/5...  ;-)

Since my current PMC is an Altimus, it doesn't have a PMC serial port.
My older X2 sandpoint had the 8240 PMC, and it, too, lacked a PMC serial

Well, we should certainly be able to use their work.  I don't personally
have much wireless experience--just with the older 1Mbps BayStack 650s
in ad hoc mode...  I'd like to do more, though, if I can find a good

Fight from which quarter?  If it's a driver and it's a port (instead
of a "clean-room" rewrite), then you won't be able to get it into the
kernel.  It could, however, be an LKM (but there are minor problems
with LKMs right now on the PPC).  I don't know how much of the code
is driver and how much is userland.  If the code is mostly userland
with a bare-bones driver, the clean-room approach might work well--
the userland code could be put into pkgsrc and I don't _think_ there'd
be much argument on the NetBSD side.  It might also be possible to talk
the folks at SSH into releasing under a dual license.  Some folks don't
have a problem with that.  Others definitely do.
