Since there is no information about the PCI bridge on the SigmaDesigns
card I don't think much can be done (or is it the same bridge as on
the Dxr3/HW+?).

The Hauppauge PVR would probably be easier to support since the bridge is
well known. The Conexant Fusion 878A is backwards compatible to the 
Bt848/878. Only some routines for transferring data from I2S or GPIO
have to be added and one would have to figure out how exactly the data
transfer between Altera, Kfir, ADSP and 878A works on this board.
I don't know how easily this can be figured out by inspection of the 
card or by trial and error. Here some information by Hauppauge would 
of course help.

But I have never seen either of those cards (only pictures) and there 
are no plans I know of to support them right now, espcially not if not
at least some minimal technical support is provided by the manufacturer.
