There's the VGA interface. Any tweaks you want to add, add.
WOW
To enable 18b VGA you need one GPIO. Adding 24b capability requires a second GPIO. The circuit as drawn uses GPIO3 and GPIO4 to not conflict with the earlier schematics which use GPIOs 0,1,2 to drive the Ethernet port LEDs.
How about putting those VGA GPIO on an I2C extender to keep GPIO free for something that needs GPIO? - Just a thought :-)
