Unfortunately not. If it's not clear from the code, point me
at the specific chunk of code you don't understand and I'll
add comments to make it clearer.

Bob Pflederer has it working and I committed his one line fix
to ccio-dma.c yesterday. I haven't tested it as my C200 is being
shipped to someone else now.
Changes to lasi LAN (82596?) and cache flushing code are also
needed to make the system usable.

You people wanna give a guy a chance to learn the architecture?
