FreeBSD 6 SMP APIC lock up

I decided to spend the day upgrading my Dual Pentium Pro 200
system from FreeBSD 4.9 to FreeBSD 6.0 RELEASE. Unfortunately,
it looks like my system is no longer supported..... 

With APIC and SMP compiled into my custom kernel (essentially
GENERIC with SMP and a lot of stuff turned off), I get a lock
up during boot:

...

unknown: <PNP0303> can't assign resources (port)
unknown: <PNP0c01> can't assign resources (memory)
unknown: <PNP0501> can't assign resources (port)
unknown: <PNP0401> can't assign resources (port)
unknown: <IBM37a0> can't assign resources (port)
Timecounters tick every 1.000 msec

.. Locks up here ..

If I use GENERIC with APIC, I can get past this point, but
the system is VERY slow. It takes an hour or so for the
system to completely boot to the login. !!

With GENERIC and APIC disabled, the system works fine and
boots to the login at a normal speed, about a minute. But
no SMP of course.

I have played endlessly with the BIOS options, disabling
all unnecessary options, etc, with no luck. Also, there are
no upgrades for my BIOS.

Any ideas/hints/suggestions? I would hate to have to go
all the way back to 4.9!

Thank you,
