Huh. I'm using the very same driver. I think it varies from TV to TV (and 
video card to video card) what gets accepted. I had another nVidia card 
hooked to this TV at one point that refused to do more than 800x600, while 
the current card has no complaints about doing 1024x768.

That's what I'm using as well.

If it is supposed to do 800x600, you might try Options "NoDDC" in the display 
device section of XF86Config. I believe if you've got HorizSync and 
VertRefresh locked to those values, you shouldn't be able to fry the TV 
(caveat emptor ;-).

I'd say absolutely. =)

No problem. And if I didn't already include the link, here's where I've 
detailed my journey down the HDTV output path:
