One of our fearless engineers got this beast to work. As I understand it, there are some quirks regarding the simultaneous use of ISO and ATL transfers which he worked around by resetting the ISP 1161 chip. He posted its' availability to the arm-linux group, but not here. Oops. Details are available at http://boundarydevices.com/usbpatch.shtml. I'm not sure how much is arm-specific, although a lot of his efforts concerned getting DMA to work on a PXA-255.
