A 32 bit PV Xen guest must have PAE (large physical addressing) enabled in the kernel and so the 32 bit the netboot/xen image uses a PAE kernel. The plain netboot kernel is a 486 non-PAE kernel for compatibility with the widest range of native machines. There is no PAE/non-PAE distinction on 64 bit, all 64 bit kernels are effectively PAE already. So on 64 bit netboot/xen is actually just a symlink to the regular netboot, the only reason it exists really is for parity with 32 bit (i.e. it's easier to just unconditionally say "use netboot/xen on xen").
