I have the same problem on an Acer Travelmate 233 XC (same model).
The system gets really heated under kernel 2.6.7, while under 2.6.3 it
runs much cooler. Also I see from metering power consumption that 
it seems like the CPU does not do idle looping. It does not reach 80
degrees, but something like 65 degrees is common, while on 2.6.3 the
system stays about 48 degrees. I run X on the system, but the system is
quite idle.
