[PATCH] Export available frequencies on K7 mobile CPUs

[Kronos]

Hi,
the following patch make powernow-k7.c export supported frequencies via
sysfs. I'm trying to write a scaling deamon and I need to know them.

La vasca da bagno fu inventata nel 1850, il telefono nel 1875.
Se fossi vissuto nel 1850, avrei potuto restare in vasca per 25 anni
senza sentir squillare il telefono
