Powercfg's processor-throttle settings

I've noticed, especially on my laptop where it matters most, that
Windows XP's processor throttling settings tend to go missing after some
unspecified amount of time has passed. These are the advanced settings
that can only be set through the command-line utility powercfg.exe, but
not through the standard graphical utility. After a few months, I often
find that I need to reset the throttle settings on various schemes
because they've somehow reset themselves to default. Powercfg is a bitch
to use, more so than most other CLI utils in general: extremely finicky
about the order of command-line switches, etc.

Any idea what causes just these throttle settings to get reset, but the
rest of the settings are totally fine?

Using it properly is often the key:
