SRU justification:

Impact: Newer 45nm model 17 CPUs ("Penryn", such as Intel
q9300,q9450,Core 2 Due E8200,E800, etc) are not recognised by coretemp
driver. 

The patch attached is straight forward upstream
cherry pick of commit ae770152c801f10a91e5e86597a39b5f9ccf2d0d from
2.6.25.

Testcase: Without the patch, the coretemp driver returns:
FATAL: Error inserting coretemp
(/lib/modules/2.6.24-xx-generic/kernel/drivers/hwmon/coretemp.ko): No
such device

With the patch, the driver recognises the CPU and loads.
