6137f591ed Don't attach to non Core CPUs. This is needed because on the PIII, 
querying the number of sensors returns > 0.

8f9a1372cf Disable the check for errata AE18. On MacBooks (1,1 version) there's 
no problem with coretemp and C3 state.

fcec3dfa48 Add a driver for the on-die digital thermal sensor found on Intel Core 
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.
