An FYI.  I ended up having to fix a few things with this patch.

First, you forgot to add '!' to the disassembler.

Second, the assignment to "testname" for the media tests was wrong (it would
say "purge tests" :-)

The address for the last instruction in the media tests was wrong (14 instead
of 18).

Finally, you didn't check for the right number of test matches in the media
tests.
