Yes, this is the only way to boot from legacy HD/CD. Refit is using
the same method, but it also writes an embedded syslinux mbr to the
disk, and mark the partition as active, this is how it boots from
different partition.

It can boot both x86_64 and 686 kernel from 64-bit EFI firmware, while
previously it can only boot x86_64.

You should also run ./autogen.sh to update the mk files. Also, I have
uploaded an binary version at:

http://grub4dos.sourceforge.net/grub2/grub.efi.1

You can use it if you still can't compile it successfully.
