I'm looking forward to seeing if 2.6.39-rc does better, then, once the 
merge window has closed and openSUSE's Kernel:HEAD has it.

OK, did that (needed to switch to the other KERNEL_BUILD line in the 
Makefile, but fortunately I'm familiar enough with those Makefiles from 
Mozilla work).
FYI, here's the sensors output and used kernel version on my Intel 
DH67CL board:

I hope those values are somewhat reasonable for what you'd expect. 
Thanks for your work on this!
