OSDL DBT-2 AS vs. Deadline 2.5.69-mm3 2.5.69-mm2

We're still working on fixing up the aacraid driver to avoid bounce
buffers, but here is data on 2.5.69-mm3 (and 2.5.69-mm2) for a before
picture.  I also have some tests queued up on STP for 2.5.69-mm3 where I
set the TCQ depth to 2.  Hopefully I will have results for those tests
later today.
