[CentOS] CentOS 5 + Xen + cpuspeed

Hey,

I know xen doesn't really support cpu frequency scaling... but... I still 
need to have it working.  Running at max speed on a laptop simply doesn't 
cut it.  I'd be okay with any solution that would allow me to manually set 
the cpu speed (intel core duo) probably from within domain 0.

Has anybody messed around with this?  I've found some patches (rather 
trivial) that apparently enable cpufreq to work on dom0 in xen for amd 
cpu's.  Anybody know of a ready-made solution for intel?  or do I have to 
roll my own kernel patch/compile/etc (and figure out what and where to 
patch)...

Cheers,
Maciej
