Well, in the 2.4.x kernels, the P4 gets compiled as a I686 with NO special treatment :-) (Not even prefetch, because of an ifdef bug) The P3 at least gets one level of prefetch and the AMD's get special compile options(arch=k6,athlon), full prefetch and SSE.

Hmm, P4 2.4Ghz , also gcc -O3 -march=i686
