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
