I would like to share the files of the next revision, but I don't know when I'll do that.
The current revision has some components that are really expensive, and there were a few issues left to be fixed.

That's true, I mostly designed this to use V5 5500 AGP cards in newer systems. The oldest MB I tested the adapter in was a socket 478 one, and it works fine. For older systems, yes, a pci-pci bridge would fix any issues.
