It was far from trivial - there's many places in the build process
which do things quite differently depending on whether it's a DTB
build or not.

That probably explains why there was no output.

It seems that - yet again - the mmc devices have swapped themselves.
Also looks like the nonfunctional video stuff is even more nonfunctional
than usual:

omapdss DSI error: can't get VDDS_DSI regulator
omapdss HDMI error: can't get VDDA_HDMI_DAC regulator

ASoC looks dead too:

omap-abe-twl6040 sound.10: ASoC: CPU DAI (null) not registered
omap-abe-twl6040 sound.10: snd_soc_register_card() failed: -517

Hmm, I thought I had, but it looks like I never pushed the change to
the main site.  I'll do that at some point.
