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.
