This is from the dialog in Boot-Up manager:

"a simple client controls CPU speed and voltage using the sysfs
interface to the CPUFreq driver in v2.6 Linux kernels.  It does not
depend on APM or CPI, and it doesn't try to do anything other than
control the CPU.

"The name is somewhat misleading, as any CPUfreq capable processor will
work,  not just those from AMD.  However, it works better on CPUs that
support more  than two speed steps, like those with AMD's PowerNow! or
Intel's Pentium M  series."

I'd like to tease the issues out in detail, but I have a deadline at the

You should find a significant amount of the information for which you're
looking at

I can pick this up later and would like to do that.
