Hmm... Not quite like that, I think.

I think you have to have both devices in the omap_dss_board_info, and
you have to have the drivers for both devices loaded when omapfb starts.

But you don't necessarily have to use the second driver, and you could
have its enable() fail if the expansion board is missing.
