Amusingly enough, I just got one of these today.
(AMD Athlon(tm) 64 X2 Dual Core Processor 4200+)

Mine also seems to stick at 1ghz on both cores instead of ramping up
to 2.2ghz (as the cpus are able to).

It looks to me like a bug in the 'ondemand' cpu govener...
If I simply change to performance:

echo "performance" > /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

It goes to 2.2 and stays there. ondemand seems to never raise from the
lowest possible speed here.
