FWIW, there is a syslinux module named ifcpu64 that will load different
kernels/initrds based on whether the cpu is 64-bit. I use it in
pxelinux at our school so our 64-bit Fedora image automatically gets
installed on the systems that can support it, while our 32-bit Fedora
image gets installed on the rest.
