Sorry to report another failure..  system is a "HP Vectra Xu", dual
PPro/200.  

Booting the floppy images, cpu's report as family 6 model 1 step 0,
most of the rest of the cpu probes look like what others have posted.

the boot cpu0 is apid 1, the other cpu1 is apid 0; seems it's not
uncommon from reports here.

Then:

ioapic0 at mainbus0 apid 16 (I/O APIC)
ioapic0: duplicate apic id (ignored)
panic: can't deal with all-ioapics interrupt yet!

I didn't notice anything else at this apid address, though the top of
the kernel initialisation messages scrolled off the screen too fast to
read.  

I don't have a nice way to get dmesg output off there, but can resort
to non-nice ways if necessary/useful.
