Ok but that means we need a way to know that an explicit -boot argument
was passed vs. the default built-in list. I don't think vl.c gives us
that today, does it ?

Hrm... might apply ... or not. If we can specific an explicit qdev on
qemu command line, then it's going to be an interesting exercise to tell
SLOF about it (PCI devices come to mind).
