Working (not the same cpu) for me on 2.6.35-29-generic:

vendor_id	: GenuineIntel
cpu family	: 6
model		: 23
model name	: Pentium(R) Dual-Core CPU       T4300  @ 2.10GHz
stepping	: 10
cpu MHz		: 1200.000

and

vendor_id	: GenuineIntel
cpu family	: 6
model		: 23
model name	: Pentium(R) Dual-Core CPU       T4300  @ 2.10GHz
stepping	: 10
cpu MHz		: 2100.000

$ uname -a

Same with Natty. Your initial posts indicated that you had battery/power
issues.

Is that still the case? Maybe these will help?

You mention in your bug report "works perfectly with kernels up to
2.6.32-24". But your last post: "Still not working with latest release
kernels: 2.6.32-32 (Lucid)". So I'm confused - with which kernel *is*
cpu scaling currently working on your machine?
