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
