David,

I believe the answer is in 
http://wiki.xenproject.org/wiki/XPDS13_BoF_Notes_:_Seeding_an_Android_and_Embedded_ecosystem#Missing_Pieces_for_a_complete_Android_system_on_top_of_Xen

As far as I understand, Android requires functionality to be made 
available via userspace drivers. These would sit on top of the kernel 
drivers.
