Have you tried using the top program to see if you have any runaway processes?
I've completely shutdown graphics (sudo lightdm stop), run powertop and i7z and shut down some offenders (like the sound modules) and still I've got high temps. Here is the output from powertop:
Code:

What kernel are you running? Here is mine from uname -a:
Linux randall-MacBookAir 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
and my current readings:
Code:
coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +64.0°C (high = +86.0°C, crit = +100.0°C)
Core 0: +65.0°C (high = +86.0°C, crit = +100.0°C)
Core 1: +63.0°C (high = +86.0°C, crit = +100.0°C)
applesmc-isa-0300

Exhaust : 3812 RPM (min = 3806 RPM)
When I'm running OSX in the same environment, my core temps are 50C (15C less!).
