Here are some news of the port.
After some weeks of abandon, I return to the project. As I am alone to develop, the project goes very slowwwww.
The current difficulty is being solved: you will have next days a read-only working smc driver for (normally) all cards from 4 to 128 MB.
The next step will be to validate it as read-write driver.
Help from motivated developers is still needed....
