Btw., here's what i stumbled on regarding HDTV out from Radeon:
It describes Windows, but there is a proprietary driver for Linux as 
well, and from
i conclude that 3D and hardware acceleration, as well as dual-head, and 
S-Video are supported. They also mention a control panel on Linux (i 
hope it carries at least 70% of its Windows capabilities). ;)

I can't wait to see if all this would actually work on my new laptop: 
probably not, cause i'm not supposed to be lucky. ;)

Anyway, the guide above says that DVI-I, ATI component video adapter to 
DVI-I or VGA connector, and then S-Video, in that order, are the best 
ways to do HDTV from Radeon, which i'm sure are ordered the same in 
general. What this means is:
if component video adapter to DVI-I or VGA connector is easy to find and 
doesn't cost a fortune, S-Video port in laptops and even desktops is an 
unnecessary expense for users who plan on using their laptop/desktop 
only w/ HDTV, as opposed to regular TV. I guess higher end boxes have 
S-Video by default, and it can't be taken off, but in general this looks 
like a good piece of info to know.
