Mmm... I get the same error in my wheezy (intel/32 bits) when loading 
the module.

At least from the changelog of cpufrequtils I can't guess what could 
have happened :-?

http://packages.debian.org/changelogs/pool/main/c/cpufrequtils/cpufrequtils_007-2/changelog

So maybe this is something coming from the kernel side but I don't know 
what it could be. Anyway, if it was supported before (with no additional 
intercation from your part) it has to work now, maybe you should report it.
