I'm not sure things like 4xx implement them "as-is"...

The problem isn't with those properties, but with the
"min-clock-frequency" property that is used by the cpufreq code
on those machines.
Note that I posted 2.4.20-ben6 yesterday with a workaround for
the above problem that might work.
The "cpu" node says:
clock-frequency 1fca0554 (533333332)
bus-frequency 07ef4594 (133121428)
config-bus-frequency 07e8fe70 (132710000)
timebase-frequency 01fbd165 (33280357)
force-reduced-speed 00000001
min-clock-frequency 032d4b20 (53300000)
max-clock-frequency 33ad5ec0 (867000000)
processor-to-bus-ratio*2 00000008
rounded-clock-frequency 1fb5ad00 (532000000)
recalced-clock-frequency 1fbd1650 (532485712)
