Very serious cooling issues CURRENT/STABLE

Hi list(s)
Early in the year I noticed CURRENT failed to cool my frankenstein 
Thinkpad T40 (built from T40/40p parts) under load.  The system would 
shut down from critically high temperatures while building a port.  I 
did nothing special with ACPI.  I thought nothing of it since, after 
all, I rebuilt a broken T40 from T40p parts.  Today, however, I noticed 
that a very recent STABLE build failed to keep my T43 cool while 
building ports.  It reached temperatures of 97, 98, 99C.  It used to 
reach a max temperature of 80C while building a port (idling temperature 
is ~ 45C).  It behaved normally from 5.3 all the way through 7.0.  To 
remedy both issues, I had to underclock the processor (via dev.cpu) and 
force the fan to its highest (I'm running 533MHz shy of the processor's 
full potential, with a fan level of 7 to keep the temperature at ~75C).  
I've always suspected FreeBSD's ACPI didn't work properly on Thinkpad T 
series laptops (I have T40, T41, T42 and T43) as it could never fully 
use the fan (Windows XP can rev the fan far higher than acpi_ibm's level 
7).  Between STABLE and CURRENT...something seems very wrong.  These 
systems never had cooling issues with FreeBSD before.

I attached my dmesg and sysctl for hw.acpi, dev.acpi_ibm, and dev.cpu 
for both machines.  I don't think the latter three pieces of information 
will be useful but I could be wrong.  Let me know if there is any other 
information I can provide.

Best Regards,
Nathan Lay
