Your dmesg:

OpenBSD 4.2-current (GENERIC.MP) #1481: Tue Nov 20 11:14:54 MST 2007
   deraadtamd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP

indicates you're not. There were some acpi improvements after Nov 20,
so it is worth trying a newer snapshot.

Not good :(.

And the temperature stays under control?

In that case, could you try to figure out how the temperature is being
kept under control with apm? Is there a fan that is turned on with
apm (just listen carefully and/or check for airflow in the obvious
places). Or does apm throttle the cpu speed (look at hw.cpuspeed).
