Ah, that does exactly what I want.  It says:

$ sudo mbmon -D

So... I suppose it's not a LM compatible chip I have so I can't
use lm(4), but I'm happy with using the mbmon port.  It has a
daemon mode, so I can start it from /etc/rc.local and query it
as an ordinary user simply using telnet.

I had no problem with slowness at all.  The reply cam without
delay.

Thanks a lot for fixing the port and for pointing me towards it!

Ok, I can live with it for a while I guess.

How's XFree86-4.4.0 coming along, by the way?
