I think /proc/cpuinfo won't refresh often, if at all, between reboots.
You can update manually with this command, ran as root:

	update /proc/cpuinfo

BTW: Is this possible to switch 'frequency governor' manually (say:
using a CLUI command) or does it need kernel re-compiling then a reboot
everytime??
