Now there's a place to post updates on driver support... I got the x1600 Catalysts to install (anyone else?) but it effectively does nothing... I didn't try it without any hacking so perhaps I did nothing, but I edited some inf files and included strings for the iMacs model (7c05) and they applied no problem via device manager and its not listed as 'fully functional' under "Displays" ... but if you goto properties via right clicking the desktop the xom is still being utilized and via non-plug&play... I think narf is going to have to give us some insight on this if we're to make any progress, since he wrote the xom that is being utilized.
