There are two different versions: stable and unstable trees.
The fix for non-coherent platforms is currently only in the unstable
version, and this can't be built externally via alsa-driver build
stub (it could, but works only for x86).
You need to build the kernel by yourself to include some new
functions, e.g. clone the latest Linus git tree (2.6.27-rc4*), then
pull sound-unstable-2.6.git on that.
