Well, that may well be true.

But when I use an ATI card with my TV , I get overscan in Linux, not in Windows.

When I use my macbook (nvidia) with MacOS X on my TV I get overscan, I
don't running linux
When I use a mac mini (GMA950) with macos I get overscan and I don't with linux

==================
This suggests to me that: 

>Windows ATI and Windows NVIDIA
>Macbook and mac mini running Linux  (Seems a little odd but there you are?)
have some level of smarts to detect the TV and / or that overscan is in effect - and adjusts....

>Linux ATI and Linux NVIDIA
>MacOS X and macos
do not have any level of smarts to detect / correct for overscan


Overscan correction is also in mythtv, I've yet to try it and expect it will probably work well, however it (presumably) does not 
fix the overscanned desktop....which may or may not be an issue.....
