What does
# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
say after bootup?

Have you observed whether the frequency changes automatically when the
CPU is under load? That would be the kernel's default behaviour if your
current governor is either ondemand or conservative.
That said, I don't know which governor is used by default by Debian's
kernels.

I suggest you use just the ondemand governor and stop caring about the
issue at all. You will get full CPU power when you need it and save a
little power when you don't. Just install cpufrequtils and folle the
instructions in README.Debian.
