[PLUG] CPU Frequency scaling in PE750?

I have some oldish Dell PE750 1u units I'm starting to use with Debian 
Lenny.  Some will be mostly idle (for CPU but probably not disk), and 
I'd like to throttle the CPU down if possible.  I've been goofing around 
with cpudyn, cpufreqd and powernowd but can't get any to work.

I suspect I may be SoL, since the cpuinfo lacks any mention of "current_ 
frequency".  Can anyone confirm or deny?  Any other ideas?

Any other suggestions for keeping power use and heat down using these
