I was thinking is this 2.6.32 derived completely from Vanilla version or
only partially? I think I've seen some case where the kernel was forked
earlier and got upgraded to the upstream version only partially.

Even Peter told that those channel switching patches in 2.6.32 should
fix the playback case only, worth to check just in case are those fixes
in your kernel tree.
