Yes, this is a Linux problem (at least in release >= 2.6.22)
This happening *only* in Linux (Kernel >=2.6.22).

This problem is happening in Toshiba Satellite M45-S355, Toshiba Equium
A100-306, HP DV8000, HP DV9500, Dell Latitude D630, Toshiba M110, Sony
Vaio VGN-S2XP, Toshiba Satellite A105-S4384, Toshiba Satellite M55-S3314
and Toshiba Satellite A105-S2201 as you can see in bug report listed above.

And is impossible find wich device eats power (eaten current is too low,
and is not enought to make hot).
