Krzysztof, I haven't seen your reply about the cpu speed.
Is the cpu MHz output right? 800MHz? Or is it automatic PowerNow?
What is the max cpu speed?

Have you tried out the latest CVS code with 64bit x86-64 speedup? 
I'm curious what's the difference between 32bit and 64bit speedups.
Note: gcc-4.x still does a good job at optimizing the generic loop.
