This is not fixed in current Edgy. There is no temperature information in /proc and the MacBook slowly gets hotter even when almost idle.
With coretemp.c [1] I can see the temperature of the two cores going up to about 78 and 79 degrees Celcius and at that point the fan kicks in. The fan seems to be able to bring back the temperature to about 54 degrees Celcius (but the bottom of the MacBook still feels pretty hot) and then the process repeats. The Gnome CPU frequency applet reports 1GHz about 80% of the time, with the occasional 1.83GHz peaks (this is a 1.83GHz MacBook). This behaviour seems independent of the temperature. I guess the cause for all this is that the kernel has no temperature information available, also reported in bug #56785 .
