Ah, now I understand your question for a unified verbose handling. I guess
if someone is bored (or if there's a need in testrunner frameworks for it)
we could add a bit of infrastructure for verbose logging and similar
things. I'll add a note on our i-g-t ideas wiki page.

All patches merged, thanks.

I've missed that you've forgotten to move the test to the _M Makefile
target. Without that testrunners like piglit won't enumerate the subtests
and run the individually. I've fixed this up now.
