The spec for the graphic chip lists DTV and 1280x1024 VESA capability.

You could get better RAM usage than this with a polygon hardware sort and
z-frame like the POWER VR stuff does.  I don't know if they do this though.
Still doesn't give you 1280x1024 with 32 bit colour, but 24/23 bit would be
OK with 16/15 bit colour and 8 bit alpha.

Anything higher than 800x600 doesn't make much sense for a tv though.
