This brings up an interesting question.  How should we be testing for
payload-dependent failures on systems like the REACTS?  The possibility
of the payload causing breakage within coreboot itself was not even
considered before now.

I think what we need is a good regression test payload kernel. This is what
I"ve done on ports to powerpc and riscv. You have a simple priveleged mode
bundle of code that exercises known failure cases.

I've found plan 9  (now harvey) to be an easy code base for this, but a
smaller, lighter kernel would probably be even better.
