You can use my module with or without X (right now it only supports the older mach64 cards) The only problem is there is no way of telling X where the capture buffers are. So you might get some corruption on screen when X uses that memory and it gets overwritten by a frame and then copied back. The more memory you have the less you will notice this. (so if you have a 4 meg card, you might want to keep your resolution and bit depth down) If there was a userspace program that could allocate the end of video memory there would be no problem.
