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.

I've been noticing under rawhide with my single core Intel Pentium M
that the cpufreq applet reports On Demand and that it only seems to swap
between 600 MHz and 2000 MHz with no steps in between, 30% to 100% to
30% to 100% back to 30%. It used to ramp up and down based on demand but
now just jumps to either extreme. Maybe it's more efficient this way?
