Jan's specific concerns are relating to interrupts, NMIs and machine-check
exceptions, if we return to real-mode at arbitrary times after the machine
has finished booting. Those concerns are quite reasonable (but, I think,
work-aroundable). However, doing one or two calls back to real mode before
dom0 even starts to execute should definitely not be a problem - that's not
what is being argued against here.
