I doubt that you'll get any support from nVidia unless they can make a
ton of $$ off your project.
VIA will get you hardware specs once you make it into their trusted
circle or unless they can make a ton of $$ off your project, which puts
you into their trusted circle.
AMD is great with specs but they only offer their chipsets as a
reference and have no long term plans to support them.
Checkout ALI or consider rolling your own with a Xilinx or Altera FPGA.
USB from an FPGA is usually the only big catch. A PCI 2.0 4-port host is
under $5 but adds to the real estate. PLX also has a HyperTransport to
PCI-X bridge. There are a few more things on the horizon but still under
