I think that means that the cpufreq kernel-patch is not able to control
the processor speed. But ACPI may be able to do so.

I have a Mobile Intel(R) Pentium(R) 4 - M CPU 2.00GHz and I am getting
the same message, when using a kernel with that patch.
But I am able to throttle the CPU via ACPI-Interface by doing
echo "7" > /proc/acpi/processor/CPU/throttlin
or any other number between 0-7.
