Maybe it will be of some use to somebody. During some emerges my machine was getting locked up when cpu temperature got above 55 C (AMD Athlon 2GB), but I decided (yeah - decided ;-) that CPU is not the problem - 55 C is pretty low for CPU I think. As a workaround I have limited the RAM amount available (I have 512 MB physical) to 256 MB by kernel parameter mem=256M. No RAM errors were detected by memtest, but limiting available RAM works - no lockups. The 'sensors' utility (part of lm_sensors package) shows that one (out of two) temperature sensor is a bit too hot: it has now (no emerge in progress) 61 C and warning threshold is on 48 C. I assume that it is not CPU that gets too hot but that small, nice north bridge on my mobo. May it be that the solution is to get some bigger heat sink and more powerful fan not only for CPU.
