You can do something like

if search --set root --file /boot/grub2/grub.cfg ; then
  configfile /boot/grub2/grub.cfg
elif search --set root --file /boot/grub/grub.cfg ; then
  configfile /boot/grub/grub.cfg
elif ...
  ...
fi

If xen provides way to pass arguments to kernel, it sure could be
implemented as arguments to grub. Actually someone asked for a way to
pass arguments to grub on EFI, so this could share implementation.
