Pygame isn't quite ready for this, I think the OpenAL suggestion would
be a better lead.

If you are set on using Pygame, it will require a bit of work. I'd use
ALSA to link the two sound cards into a single sound device. SDL
recently added support for 4-channel audio, but it will require a small
tweak to the Pygame api to pass in the right values. From there, I'm not
sure how the panning would work. SDL_mixer includes a stereo panning
filter, but I don't think it handles more that 2 channels?
