Dr. David Alan Gilbert ea0c6d6239 test: Postcopy 
This is a postcopy test (x86 only) that actually runs the guest
and checks the memory contents.

The test runs from an x86 boot block with the hex embedded in the test;
the source for this is:

and that can be assembled by the following magic:

    objcopy -O binary fill.o fill.boot
    dd if=fill.boot of=bootsect bs=256 count=2 skip=124
