Matt,

	So far so good.  It boots up, and it stayed up for about 30
minutes while I did a "make -j4 buildworld".  Unfortunately, the CPU
temperature rose above 60 degress Celcius, and the machine shut down :-)
I'll give it another go later, making sure it can stay up for at least
24 hours :-)

Adam
