I don't have all the time in the world to set his computer up perfectly, just the time to make sure it is relatively bug free and he can check e-mail, etc. I have too many of my own hardware troubles to worry myself with fully optimizing everything he has. I'll make sure to recompile the kernel after the installation, though.

Since the laptop came with no OS, I never bothered to put Speedstep on when I added WindeXP. Consequently, my mother's PIII laptop also does nothing of the sort, even though it came with Windex ME. I installed XP for her, Speedstep for ME was incompatible, and she still has her two hours of battery life without Speedstep.
