Hi! I have an iBook2.2 with debian woody, running a 2.4.20benh Kernel. Well, the iBook is known for its spare use of energy. Certainly true. But of course the hardware depends on features of the OS to support minimal energy usage. While Linux is definitely not bad I got the impression that MacOS X is still doing a little bit better. The reason I'm thinking this is that the surface left to the trackpad is noticeable warmer when running Linux. Maybe I'm missing something? Some setting besides that in /proc/cpufrequ to reduce energy comsuption a little bit further?
