Is this on a 1.5 or currentish machine?

Heh; that's what I'll be using mine for, too.  We need a *reliable*
machine to provide console services for our linux boxes.

Incidentally, we're using an Intel L440GX+ motherboard (from VA Linux,
actually) for these Linux boxes.  It has an "Emergency Management
Port" (EMP), which is a serial port with a dedicated, always-powered
circuit attached to it.  The EMP can power-up, power-down, and reset
the system, as well as tell you the fan speed and CPU temperature.
There's some Windows software you can get to run it, and VA Linux also
makes something called VACM that'll run under Linux.  This is what I'm
running on my NetBSD box, under COMPAT_LINUX.  The big drawbacks are
that it won't run unless it's under X, and it's linked against gtk.
So I'm going to be running an X server using vnc, which I can then
attach to.  The code is not, IMHO, well-written -- it did not want to
compile under NetBSD, and it has some gnarly Linux dependencies in it.
But it works.

I'll try that out; thanks.
