Greg. Take a run down to your local BB and take a look at the card. Given that AMD/ATI have put hdmi out on their igp chipsets and it is in the spec for the 3800 I would be very surprised if it wasnt on the 3000 series cards.
FWIW, that MS white paper stated that the initial release of Vista would not support True HD and HD-DTS. That suggests that there were/are significant challenges in passing it through the pc in a 'safe' (as MS likes to put it) manner. There is a possiblility that MS still dosn't have the drm code in place to do this reliably. The paper did say that handling both video and audio posed significant challenges (they are authenticated and DRMed through separate channels/processes.
