Can you check whether or not you were also using p4-clockmode with the 
last kernel that did show correct values? The same grep command should 
show this.

It would also help to know which kernel version was the last working one. 
You mentioned 2.6.26, but with some uncertainty. Can you check for 2.6.26 
and possibly for 2.6.27?

Note that p4-clockmode does not really help with power saving, but only 
with thermal management (prevention of overheating). Possibly the 
speedstep or acpi-cpufreq modules will work better for you, but it can 
also be they don't support your processor.
That does not mean this issue should not be looked into of course.
