Can you please clarify a little bit what's special in the 2.6.32 about
dma on ss4000e ? For instance, iirc, the iop-adma driver has been added
in the kernel at the same time as the iop-adma driver.

hm.. I'm not sure that redboot on ss4000e is supporting usb
devices. You'll have to either wait for someone else telling you it
supports usb and how to do it or check by yourself.
Nevertheless, you can still put a kernel with usb support built-in in
the ss4000e flash and change the kernel command line to boot on usb.
