Is this one shipped with a 82815 northbridge?

Under Linux we had report of some bugs with an i8000 and i8100
some times ago, and therefore we disabled speedstep support.  I think
Nate correctly disable it under FreeBSD.  I'm not sure if the
i8200 is touched by this bug though.
IIRC, it was possible to use the SMI stuff, but this worked only
for the i8100.  Now, I just remember I only enable speedstep
via SMI calls only if a PIIX4 southbridge is found, and therefore
speedstep may not work even though it could be possible to use it.

Please send me a dump of the ACPI tables if you can't get temperatures.
