Even if it does attach the est-driver, I don't think it receives the
correct voltage to the processor. For example on my laptop I have been
running FreeBSD i386 and now amd64 with the Core 2 duo T7700, the fan
runs constantly and it feels hot where the processor is located. This is
not the case when running for ex Linux.
