It fails. :( > This patch set fixes the binder interface so that it works on 32/32 or 64/64 systems and preps the driver for the compat layer - 64bit kernel/32bit userspace. As discussed with the Android developers the binder compat will live in the userspace. Thus for a 64bit kernel the calls coming from 32 or 64bit file-systems will look alike. Thus for the moment it won't work.
