Probably but there was config options to support this (loader +
kernel) and code in both xend and qemu-dm.

In upstream qemu, the code is present to support direct boot but the
xen implementation is quite different from the usual "qemu way", at
least for grabbing ram at start; see `pc_memory_init` which is
bypassed by `xen_enabled`.
I will see if I find time to patch the upstream qemu version.
