The only reason I can think of to have a separate FFH driver would be that we could potentially combine parts of the x86 acpi-cpufreq and the ia64 acpi-cpufreq. I didn't look closely, but the x86 and ia64 acpi-cpufreq drivers looked pretty different, even apart from the FFH stuff, so maybe that wouldn't be feasible.
