it is definatley a widescreen. 6600GT wants a 1920x1440 to output 1080i and an 800x600 to output 480i. virtual screen size as reported by X for 1080i is 1920x1440 and 2306x1024 when I run in dual head mode with the nVidia set to output 480i. I have very little doubt that this is being managed by th 6600GT for both 480i and 1080i. How is up in the air. I would think this has more to do with the hardware implementation than the driver. Though maybe not, the 5700 took an 800x600 to the SVIDEO to do the same thing on the same widescreen TV. I'm presuming there is off screen stuff because I have to scale myth to a virtical resolution that is less than 600 (800x524 at the moment, which is something more than the vertical spec of 480 and something less on the y side of 852) to keep it from dropping the "cancel", "back" and "next" buttons off the bottom of the screen. when in 1080i mode I scale it to 1920 x 1084 with some x and y offsets to fit the screen the way I like.
In an ideal video world, the screen resolution of X and the TV Output scaling should line up. I have not discovered this panacea with my rig, for whatever reason, probably because I don't want to risk my TV jacking with modelines even if it is 4 years old now. It seems a bit strange to me as well, but it works so what the hay,... Hopefully, the newer HDTV's with native resolutions of 1280x720 (720p) won't exhibit this weirdness. either that or the X community will come up with more interesing modelines for HDTV's as they become more popular in the myth type context.
