I guess you are included the hypervisor and dom0 kernel in your pressed file in the list of extra packages to install? update-grub already supports creating entries for Xen dom0 if a hypervisor and suitable kernel are found. This functionality was only added to grub2 quite recently and I'm not sure if it has migrated to testing or not yet. Perhaps all you need is a preseed post install script which modifies the default line in your grub configuration? Otherwise I'd suggest that you could file a wishlist bug to sort Xen before non-Xen options when Xen is available (IOW rename /etc/grub.d/20_linux_xen -> /etc/grub.d/09_linux_xen). Alternatively perhaps the default could be made selectable via debconf (which you can pressed), although perhaps on fresh install only.
