What does your RAM map look like now from early Xen boot, using
no-real-mode? It shouldn't be "Xen-e801" any more at least, else the
no-real-mode parameter isn't working.

The installer probably added 'placeholder' because older versions of Xen
skipped the first argument (because on old GRUB that was the path/to/grub
rather than a real argument).
