I don't expect xresprobe to be hard.  There are two parts which will be
  a) making the xserver-xorg scripts understand multiple input and
     output devices, and
  b) getting DDC on multiple devices.

Right now we generally do DDC via VBE, which is kind of difficult when
you have multiple cards.  Doable, but really really nasty.  So what you
really want is the drivers to be split out into Xorg drivers, but also
libraries where you can initialise the card, look at its outputs, and
figure things out for yourself.  But that's, uhm, a bit of a pipe dream.

Also, one of the more difficult things to do properly is multiple
outputs on single cards, especially when it comes to laptops with
external displays.

It's not at all trivial, but fixing xresprobe is definitely the easiest
part.  Working out what you'll do about DDC, and fixing xserver-xorg;
now that's the hard part.
