Why not add a glibc and kernel which are optimized for pentium 4 in FC3 ? This would increase the perfomance on newer PC but also works on older ones by still including the i686 and i586 versions.
Starting with FC3, .i386.rpm and .i686.rpm packages will be compiled with -march{3,6}86 -mtune=pentium4, so although they will run on i386 (resp. i686), they will be optimized for P4 (Athlons and newer AMD chips run P4 optimized code without noticeable performance hit).

How does this impact Pentium-M processors (Banias and Dolthan) which are some sort of P3/P4 hybrid that gets more work done per clock cycle that straight up P4s.
I thought I heard that Intel recently announced that in the future their desktop CPUs would be using the Dolthanesque CPUs -- and aren't laptops about to outsell desktops?
Just curious, since I just ordered a Thinkpad T42p with a Dolthan cpu.
