Hm..... hard choice.....correctness traded for perfomance.... But
anyway....IMHO this hack is needed for every speed-step enabled
machine. Perhaps...the other workaround is via cpufreqd? I don't have
any Pentium M based PC/laptop around, so this is just a pure guess
BTW, your patch seems reversed....if you really mean you want to fetch
realtime clock, you should use "rdtsc", right? But the patch seems
replaced "rdtsc" with get_clock()....
Another thing, IMHO it is better to use unified format (diff -u). More
readable and i think it is a standart
