Patch: +7 -6
If xen.gz is present, there are multiple kernels, and later ones lack an
initramfs, they'll currently be (wrongly) configured to use a initramfs anyway.
Fixed.

We also refactor the check for /boot/initramfs-$tag, and configure this using a
separate INITRD line, instead of adding it to the APPEND line. In passing, this
also closes a second might-use-a-stale-initramfs bug.
