May be it's same problem we had in the past on PRIMERGY.
Extract of readme.1st
Problem: In certain configurations, a multiprocessor kernel will not
boot properly, either hanging or panicing with various error
messages.
Description: On a Multiprocessor system with a Phoenix BIOS, the BIOS
allocates a so-called Extended BIOS Data Area (EBDA) at the
upper end of the machine's 640K base memory and uses it to
store, among other things, the MP config table.
LILO, however, happily puts the second stage loader and
associated data structures there, rendering the MP config table
useless.
Solution:
Either fetch the sources of lilo v2.0 or lilo v2.1 and apply the
patches in lilo-20.patch or lilo-21.patch or use the
pre-compiled boot.b for a lilo v2.1 system. This file must be
copied to /boot and /sbin/lilo re-run.

I have the chip. This is a straight Intel system. And the EISA
config
states that it has to be turned on for SMP operation. Booting with
the APIC
turned off in the BIOS/EISA boots the kernel with only one
processor. Also
the APIC is detected by the kernel. Which brings me to another
conclusion.
How do I find Brian Perkins... He is the one that wrote the code
that my
kernel is panicing at. I am blowing right past all of his
failsafes.
