- delta - current delta reading
- resolution - sensor resolution in Celsius

This way we would have an opportunity to hide the
Tj(target) value doesn't seem right stuff if we know
it's not working there.
Add temperature value for Core2 Duo Extreme Mobile that
I have access to.
Xeon 5500/5600 series:
- Utilize IA32_TEMPERATURE_TARGET, a.k.a. Tj(target) in place
of Tj(max) when a sane value is available, as documented
in Intel whitepaper "CPU Monitoring With DTS/PECI"; (By sane
value we mean 70C - 100C for now);
- Print the probe results when booting verbose;
- Replace cpu_mask with cpu_stepping;
- Use CPUID_* macros instead of rolling our own.

make sure to never call sched_bind() for uninitialised CPUs.

and newer CPUs (including Core 2 and Core / Core 2 based Xeons). The
driver attaches to each cpu device and creates a sysctl node in that
device's sysctl context (dev.cpu.N.temperature). When invoked, the
handler binds to the appropriate CPU to ensure a correct reading.
