Doesn't matter - it's probably only calibrated at startup. Run
bogomips (the application) and compare.

So it seems that you are running at 800MHz.

Then make one. You will need to load various cpuspeed support modules.
apm 21224 2
speedstep_ich 7944 0
speedstep_lib 7552 1 speedstep_ich
freq_table 7936 1 speedstep_ich
