That seems warm, but not dangerously so.
Maybe you've got something running that you're unaware of?
The Pentium M has a downstepping temperature of 99*C, and an auto-shut down temp of 125*C, according to their website.
So the CPU can handle fairly high temps. In my nooby opinion, the concern is really whether the motherboard on which it sits can handle those temps.
Have you looked in Task Manager to see what else might be running?
And do you have Intel Speed Stepping enabled? (That's in your BIOS.)
If it's disabled, the CPU stays at low speed. I do not know if that would make it run warmer while trying to handle more apps.
