Yes. It does give me a few more gray hairs, though =). It'd be so much
easier to have all related changes in one clean patch series.

To make the DSS work properly after this device model change, we also
need to solve the problem related to multiple display devices on the
same video bus.

Did the approach I suggested in

http://permalink.gmane.org/gmane.linux.ports.arm.omap/96039

look ok? Overo is the most complex one, I think the rest of the boards
that require changes have just LCD and DVI that conflict. But it still
means we'll have that kind of choice Kconfig option for all those boards.
