There are no other options but GENERIC (AMD64) - I had "rtc.ko" loaded - But I have removed that
which helped a little bit (I can sit beside the machine when its running single job "make buildkernel" ).
On my standard make -j 8 it still gets very hot - which it never has done until very recently
World and Kernel was build this afternoon - I normally rebuild every day - kld loads

What are the most reliable way to get idle time? Running vmstat and sysctl dev.cpu | grep temper - seems
to indicate that the grow hotter even when idle is quite high e.g. 25-50% - but that could just be a measurement error
