Sounds fairly reasonable to me.

Make sure you have the laptop on a desk, since the R3000s have the two
intake fans at the bottom of the case and need to have some space around
the feet to draw in air. Otherwise it gets rather hot.
70C is still an acceptable temperature for the athlon 64 as far as I
know, and if that is running full out, that seems ok. It is a small
laptop case after all, and not a desktop with a giant heatsink.

I wouldn't think so.
If you have apci-cpufreq loaded, and possibly the cpufreqd program
installed, it should move the speed up and down on demand which seems to
do a pretty good job keeping it cool. of course airflow through the
laptop is the main thing needed to keep it cool. Perhaps _lap_top is
the wrong name for these things. :) I certainly don't recommend running
it in your lap.
