uh, I got the same close results (i.e no perf improvements) on my celeron 500
at home, which has this:
cpu0: features 183f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR>
cpu0: features 183f9ff<PGE,MCA,CMOV,FGPAT,PSE36,MMX,FXSR>

I guess all what's needed is here ...

Either something didn't get enabled (althout I checked that LARGEPAGE is
defined), or this isn't as good as it looked :)
