To my knowledge, Syslinux has not been tested on ia64. Despite the fact
that it uses a version of EFI, I very much doubt it would work out of
the box without quite a bit of hacking.

You can explicitly build Syslinux for only the architectures you care
about using, 'make bios', 'make efi32', etc. It's just that by default
'make' will build for BIOS, EFI 32-bit and EFI 64-bit.
