Much thanks to all who replied.

Yes, MPS Version 1.4 is apparently required for 1.6 MP to work
properly, and yes, there was a bios setting to choose it that we
had missed.

The only problems I have had with these are that the LM driver
incorrectly calculates the cpu temperatures (port-i386/18205) and
XF86 appears to be somewhat unstable. It appears to simply lock up
the cpu it is running on - no core dump or anything. If XF86 locks
up cpu1, cpu0 can still conveniently restart the machine, but if
it is running on cpu0, the whole box appears to lock up. Is this
consistent with known status?

We will be primarily using these boxes as compute servers so XF86
shouldn't be a real problem, but wanted to try them out as desktops.
Pretty impressive, as long as X stays up :^)

Thanks again
