Sadly, while the DVI connector is the same, the standard is not, so you probably* can't plug it directly into a VGA card. I was psyched to see the connector on my HDTV when I bought it, but then the manual explained that it is NOT for use in connecting to a PC. The HDTV signal is expecting 480, 720 or 1080 scan lines at 60MHz, and except for 640x480 you haven't got an exact match.
Search for "EnTech PowerStrip" to get all sorts of info on this, and beta on an app that will allow you to get some cards to output non-standard (in terms of VGA) formats that'll look right on an HDTV.
* Caveat: I'm sure someone will come back and say the HDTV they bought includes a scan-converter and does do this, so check your manual if you are unsure.
