And tested on a core2 laptop, when idle:

model name	: Intel(R) Core(TM)2 CPU         T7200  @ 2.00GHz
cpu MHz		: 1000.000

and when burning:

model name      : Intel(R) Core(TM)2 CPU         T7200  @ 2.00GHz
cpu MHz         : 2000.000

Working perfectly fine (Dell Inspiron 9400 + 4GB RAM, 64 bit natty
with Linux photon 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24
UTC 2011 x86_64 x86_64 x86_64 GNU/Linux).
