The kernel you paniced with is from Feb 2008.  It would be helpful if you
could try either a BETA4 kernel on your AMD64 machine, or a Feb 2008
kernel on your i386.

Also note, if these two machines are different, they can easily have
different hardware and thus trigger/not-trigger the problem just due to
the HW differences.
