okay.  if you have a chance, with the 9atom cd that boots to rio,
can you try dd'ing from the /dev/sdE? you can just open a new window
in the installer.

        ; ramfs
        ; dd -if /dev/sdE?/data -of /tmp -count 100 &&
                dd -if /tmp -of /dev/sdE?/data -count 100

also the output of

        ; cat /dev/sdE?/ctl

and
        ; pci

and
        ; cat /dev/irqalloc

would be helpful.
