: I have not looked at details, but it looks like whipping up a plugin for
: gkrellm for this would be pretty straight forward. It has all of the
: basic tools to do what you want. It already monitors environment from

: information is not available in ACPI.

How do I get the current speed of the CPU?  The rest I think I can do
already...  Is it just the dev.cpu.0.freq?  Is there some way I can
test this value easily to make sure that the OS' idea of the speed and
the CPU's idea of the speed are the same?

I've seen a lot of interesting graphs in the windows arena that seem
like they would help battery life a lot w/o compromising performance
all that much that I'm thinking would be fun to code up...
