2.6.27: 0 MHz CPU and wrong system time on AMD Geode system

[Antipov Dmitry]

After updating the kernel to 2.6.27 from 2.6.25.4, my system time goes wrong and
CPU becomes 0 MHz (as shown by /proc/cpuinfo), probably due to these issues:

TSC: Unable to calibrate against PIT
TSC: No reference (HPET/PMTIMER) available
Marking TSC unstable due to could not calculate TSC khz

The hardware is http://www.fit-pc.com/new/fit-pc-1-0-specifications.html,
and the base system is Fedora 9.
