Right.  I did consider putting a closer-to-conventional RTAS blob in
kbm-unit-tests' special "firmware" (which currently consists of a
single jump instruction).  It does help to build it BE which RTAS
expects.  On the other hand, I wasn't about to implement a full OF
client interface, so it would still have the main part of the tests
relying on finding the blob at some well known location.  And finding
a well known location that we can count on the tests proper not
clobbering is a bit of a pain as well.
