Very little to none. If you mean something like this:

it would mean touching a lot of places.

This has been on my TODO for a long time. Standard image will fail, it
probes for QEMU. But it should be possible to create a special entry.S
for real hardware. There are some other places where we just use the
Qemu facilities directly without probing for the real alternative,
these should be fixed.
