Why would you want "only" the DVI-D card?? The DVI-I handles both digital and analog.
Check out this link for a great article on DVI-D and DVI-I:

The difference is essentially that the DVI-D connector features only the 24-pins necessary for purely digital operation while a DVI-I connector features both the 24 digital pins and the 5 analog pins.
I believe these cards should have
DVI-I outputs, I'm sure there are more:
MSI Ti4200-VTD8X
ATI Radeon 7500
