The numbers you report for buildworld time are roughly on par for my 233mhz 
box here, on a good day.  It's a kick-off-the-build, leave-for-work, 
come-back-after-dinner sort of box. :-)  But my point is, that reported speed 
might not be so far off, for whatever reason.

I couldn't tell from your dmesg if you're using ACPI.  If not, does enabling 
it (on a recent -current) help?  I've been running into strange situations 
with CPU throttling on my machines here, though a throttled CPU still reports 
the right speed for me....
