It looks to me like the fastest way to test the GPIO lines connected on the micro-desktop board to VESA_SCL and VESA_SDA would simply be to connect a VGA monitor to the micro-desktop and make sure it is properly detected and a test image looks right on it.
yep, pretty much... with one slight fly in the ointment: the SCL and SDA lines are straight GPIO and will need a bit-banging I2C linux kernel driver. once that's configured, doing i2cdetect _should_ be enough to test the circuit, although scanning the data and running read-edid on it would be awesome and amazing: it would mean being able to *really* do proper VESA detection.
