In addition we should really bring in NetBSD's est code.  I have heat
issues with an older laptop (read non-Core 2) that are mitigated by
lowering the frequency for prolonged CPU intensive operations.  I
started working on bringing this in for support on my Core 2 laptop
but am in the middle of final exams.
