In Xen we get image offset from GRUB2 and using this value we calculate
relative addresses. We are using %fs for it.

This is another option. We considered it too. However, in our case
relative addressing looks simpler then ELF relocations. However, if
you wish I can add this functionality when this patch series is
included in upstream GRUB2. Is it OK for you?
