Just doing a quick search before I throw down a couple hundred bucks :)

To recap:

The 915GM chipset is capable of displaying full resolution HDTV
(1080i) using hardware acceleration (so a 1.5Ghz Pentium M should
suffice) using the latest and greatest driver from git (running
Gentoo)?  The board I'm looking at:
Has Svideo, Composite and Component (as well as VGA) included with it,
an added bonus I can pick up:
To add DVI as well.  I'm hoping to be able to output HDTV over any of
those interfaces (though I definitely understand that Composite/S-Vid
isn't capable of displaying HDTV, but hoping that the hardware will
simply down res without any user interaction) using MythTV as well as
Xine and/or Mplayer.

So, is this a pipe dream, or should this work?

Any info is much appreciated!
