Subject: coretemp: Support for Intel Atom E6XX CPU (TunnelCreek)?

Hello,

I have a patch (for v2.6.39) which adds support for Intel Atom E6XX 
(TunnelCreek) to coretemp. It's merely only adding x86_model 0x26.
But there are models (e.g. E660 and E660T) with different TjMax, namely 90 
degrees C and 110 degrees C. But these different model can't be detected by 
reading from hardware.
IMO there should be some support to adjust the temperature from userspace. 
Reading Documentation/hwmon/sysfs-interface only temp1_offset seems to be 
useable. But I think it is somewhat misleading (especially on multicores), 
because there must only be one offset.
What do you think about this?

Regards,
Alexander
