Nope - it is a dual P5-133, with the ability to take quad processors.
It has a dual PCI bus, dual on-board F/W SCSI controlers and various
other server features, making it a monster of a machine (the case
alone is a monster!). :-)

That is quite likely, so Steve has been adding in a lot of extra code
to work out the exact config. Attached is a sample output from dmesg
to give you a taste of what he is up to. (Some of the values won't
make much sense at this stage because they were added as tests for
various stats)
