Is it possible to use some sort of adapter, or even to solder a device to the Raspberry Pi board to support PCI or PCI express devices? I'm thinking smaller devices such as NICs or Sound Cards. I wouldn't think there would be enough voltage to run something such as a tuner or Graphics Card.

I doubt this is possible. You would need some sort of bridge and something to connect it to.

Not sure why you would need to, NICs/Soundcards/tuners and more can plug into the USB

There are also USB video adapters if you want to add a second screen. There's not much point trying to hook up a high powered graphics card for games etc. The only reason I can think of is if you were using the GPU for coprocessing

No, it's not possible. The Raspberry Pi is based on low budget arm SoC that has only usb bus, so it's impossible to attach PCI or PCIe card to it. Neither an adapter could be made.

Maybe the GPIO pins could connect to something that can address the PCIx? It would mean a big hack and the question is. How fast can data be read in from the GPIO pins.

Not fast enough. – Jivings Oct 10 '12 at 16:59
Agreed- Not fast enough and it HAS to be realtime. Linux is not realtime. – ppumkin Oct 11 '12 at 16:14
