it would be interesting to see a i386 vs k7 comparison.
Since the architectural difference is bigger; the k7 architecture has 
some floating point extensions(3D Now) which usually have a big impact 
on performance.
Therefore we should look if the kernel can handle these well enough 
dynamically.
Perhaps it would make sense to leave one optimized kernel on i386 for 
newer CPUs.
This could be SSE optimized then to be more generic (AthlonXP+, Pentium3+)
