It looks like the problem is that Xen doesn't respect "--" to mark the
end of the Xen command line. On x86 they don't have this problem because
GRUB supplies separate boot arguments to the "kernel" (Xen) and the
"module" (Dom0 Linux kernel).

Have you tried inserting a NULL into the commandline to get Xen to stop
parsing the command line?
