Brian, the tree you reference is not for Android.  It's just a minimal tree to boot our internal SURF platform on .31.  It may have some android bits in it but they are not used.  We only validated console and the sd bus driver.  Our latest released Android tree is https://www.codeaurora.org/gitweb/quic/la/?p=kernel/msm.git;a=shortlog;h=refs/heads/android-msm-2.6.29b.  It's based on your android-msm-2.6.29 branch from back in May and has whatever dream/sapphire support you had at that time.
