That's OK; I can probably safely assume it's the M1533 device.

Ok, I think we have the enemy in sight. Can you please say:
set debug.acpi.timer_test="yes"
at the loader prompt and boot? Ideally, you'll get a message "timer is
not monotonic", followed by some numbers. If this is the case, then I
need to get "smarter" with the ACPI timer probe.
Thanks!
