I think I've just found a nice way to check whether the OpenBIOS
machines can at least successfully run through the OpenBIOS boot
sequence: You can use the "-prom-env" parameter of QEMU to execute some
Forth code there, so this can be used to signal a successful test to the
qtest environment.
Unless you've got a better test in the works already, I polish up my
patch and submit it later today or tomorrow...
