Stability with a kernel of my choice on possibly
non-x86 hardware matters most. Digital DVI, fanless
operation, and DVD scaling are next. After that, 3D.

I'm not so sure you have to give up 3D. You can put
at least 4 AltiVec-capable "G4" CPUs on a PCI board
without having horrible power and temperature issues.
(Perhaps an AGP board can safely support even more.)
Each will do 4 32-bit floating-point fused-multiply-add
operations per cycle. That's got to be good for something.
I think the latest chips have built-in memory interfaces.
They have RapidIO interfaces. So you make your FPGA
speak RapidIO protocol (easy) and have each CPU render
every fourth frame.

One could even put the X server on the card.

Ultimately, this is a huge risk, with potentially
great reward. One must take some risks to succeed,
and this one is a whopper.
