Linux router project

I have an old failing system using Linux Router Project, kernel 2.6.8, that I inherited. It is used to run a few applications, one of which uses a video capture card.
The libraries are old and I would rather not spend the time rewriting stuff for a more modern OS. I would rather try to just get it up and running on modern hardware, if it is less work.

Has anyone here tried getting LRP, or one of its offshoots, to work with PCI-E devices? I was thinking of using something like this, because it seems to be popular among linux media center systems.

Any info or assistance would be greatly appreciated.

Thanks!
