We built a setup with 4x 3dlabs wildcat 6210 cards.
These cards have genlock support.
With a Xi xserver you can have 4 synchronized stereo signals.
However, we found the driver to be unstable, with occasional kernel crashes.
Currently, we are replaceing the 6210s with an nvidia card that
has genlock support, but this is work in progress.
