really, was that surplus or from a production line.
if its a production line i would be intrested in the link
when it comes to doing 320x240 i think software is the best way to go about it, ubt i am not familliar with the inner workings of X. i suppose with a driver you could make a display adapter with both modes that toggled a gpio. the only thing i am woried about is that the graghics card drivers would need there bits twiddled.
not so hard after thikning about it. lets wait and see
