There was some discussion in -current around the time I submitted the
PR and since there's no obvious link, for the record, the following
thread is also relevant:
http://lists.freebsd.org/pipermail/freebsd-current/2004-October/039938.html
My investigating at the time led me to the following:

Unfortunately, I no longer have ready access to that machine.

I believe the DL380 supports 1 or 2 CPUs. Chen's dmesg shows that the
CPUs have APIC id's of 0 (BSP) and 6 (AP). All I can assume is that
either HP designed the machine backward or that someone installed the
CPU in the wrong socket (assuming that would work). I never looked
inside the box and no longer have physical access to it.
