This looks very much like the panic I saw a few weeks back;

http://lists.freebsd.org/pipermail/freebsd-current/2004-January/018970.html

except mine kept going on and on.  I have never seen this panic again,
and with the recent ACPI commit by John Baldwin
( http://lists.freebsd.org/pipermail/cvs-src/2004-January/017369.html)
I have not had any problems with ACPI.

I am sorry for not offering much help, but I thought I'd let you know
you're not the only one with Pentium II and has seen this type of
panic :/
