I was perhaps a bit vague, but I didn't say it should be a minor thing.
I meant that there should be no architectural obstacles in omapfb, and I
think all the generic plumbing to enable N800 display is there in omapfb.

That said, it still needs a real amount of work with the rfbi driver,
the encoder driver and the panel driver on N800 (the encoder and the
panel driver are not in mainline anymore).

Also, if I remember right, omapfb doesn't support automatic updates (or
"flushing") with manual update displays. omapfb was designed to depend
on the userspace to flush the framebuffer. This may limit its uses.

I personally do think that it would be better to target omapdrm, on top
of the manual update series, but as discussed, the schedule to support
manual update is still unclear.
