cpufreq on Pentium M

I am running on a Thinkpad T40p laptop, which has a 1.6GHz Intel
Pentium M CPU (this is their "Centrino" CPU; *NOT* the same thing as
the Pentium 4 M).

I have tried 2.4.21-rc7-ac1, but it reports:

cpufreq: Intel(R) SpeedStep(TM) for this chipset not (yet) available.

Yet my BIOS lets me configure SpeedStep for it by name. Are there any
plans in the works for this?

While we're at it, I'm concerned that Linux is ignoring the sizable
cache available on this platform:

$ cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 9
model name : Intel(R) Pentium(R) M processor 1600MHz
