Yes, there are a lot of your changes MFCed, but it's not up-to-date. I
searched through cvsweb for the fix which removed the allocation of DMAable
buffers and uses plain malloc()ed buffers. I haven't found it at a first
glance, but I don't think it's MFCed. And without this change the uaudio
device will not attach.
Ariff's patchset contains a backport of the current sound code and it is
known to work.

Life would be so much easier if we could just look at the source code.
