What a sad story.  Then Pentium 4 CPU has very little to recommend it, 
including in the arena of power management.

The help for the kernel's p4clockmod says how tragic a hack it is, since 
desktop P4s support so little in the way of power management.

Pentium M-based things, like the "Core Solo" or "Core 2 Duo" (or so on), 
have real power management features.  Then Pentium 4 "M"(obile) I know 
little about, but I have been taught to fear anything with "Pentium 4" in 
the name.
