My patches to build an xcg14 might help, but would definitely need work
(for multiple reasons - to name just the ones that come to mind
immediately, for -current vs 1.4T and for integrating cg14 support into
Xsun - the current xcg14 does not support any non-cg14 framebuffers).

My understanding is that it uses the last framebuffer found during its
POST probe.  Since it does sbus after obio, this means your bwtwo
overrides the cgfourteen.  (Of course, this is only for
output-device=screen; you can set it explicitly.)

However, this is a guess based on observed behaviour and may well be
wrong, possibly in multiple ways for all I know.
