First thing that popped into my mind when i read the
ECP2 docu is, that it has LVDS compatible pins, but OGD1
does not have any connector for them. IMHO it would be
a very good idea to have just a few LVDS sender and
reciever lines, maybe just 4 of each (16 pins) on a
connector. Those who'd want to couple two OGD1 boards
or interface with another device would be glad to have them.
If the direction of those LVDS links can be changed by runtime, then I
would vote for 9 pairs, which can drive LCD module of any size.
If you are going to take the LVDS to a connector on the back side of the
PC, wire there also 3.3V, 12V and a ttl output for backlight switching.
Otherwise this TFT-panel-hookup could be realized in form of cable
connected add-on, just like as the additional usb ports are.
