I have a new Gentoo AMD64 box on which I'd like to get the 16-port capture card working.  It's running sys-kernel/gentoo-sources-3.1.10-r1, with CONFIG_VIDEO_V4L2 and CONFIG_VIDEO_V4L2_COMMON set to build as modules.  I've pulled the driver source from the Git repo.  make builds the first few files, but then stops on videobuf-dma-contig.c.  I've attached the output from make.  I have a client with a medium-scale (about 130-140 cameras) installation built on an MPEG-2 capture card from a company that's no longer in business; I'm looking to build a replacement for them around the Bluecherry H.264 capture card, but I need to get the card working first.

As  a temporary measure, I could bring the system up with an older kernel (Portage offers gentoo-sources builds based on 2.6.32, 2.6.39, and 3.0.17) if that'll be more likely to build, but support for the newer kernels would be a plus.
