Please CC me, i am not on linux-kernel maillist
Hardware: Asus EEE 702,
CPU: Intel Celeron 900 Mhz
On 2.6.28 p4-clockmod available, and i can manage governor, frequency and etc
over cpufrequtils.
On 2.6.29-rc6 (git5 tested also) also shown in dmesg as available, but i
can't change anything.

Report errors and bugs to linux@xxxxxxxx, please.
analyzing CPU 0:
no or unknown cpufreq driver is active on this CPU
There is no noticeable differences in dmesg.
Both have
