Yes, your situation looks a bit strange, but maybe it's because of the
Compaq (or early HPaq) brand, they did strange things with BIOSes in
those days.

Apparently, the OS detects only one logical CPU (no hyperthreading) on
your system, but it looks like HTT is enabled, so this might be the
cause of your message.

In any case, you will probably not have any problems with this
configuration. HTT in those days sucked anyway.

On the other hand, you are running a CURRENT kernel with WITNESS and
other debugging enabled, so as the boot message says, expect your system
to run very slow.
