Actually the first gen 1080p sets for the most part didn't take 1080p input from HDMI, but did from component or VGA. The Samsung HLR DLP's were the first with 1080p resolution and were like this. The first mainstream Sony SXRD (not the $13k Qualia, but the grand wega) couldn't take 1080p input from HDMI either.If you were one ofthose people who bought a first gen 1080p set you should have known what you were getting yourself into.
So in terms of compatibility, I'd say component/VGA is actually better than HDMI. Of course, the latter has theoretically better quality.
