The driver is a horrible hack lacking too many of really needed error
handling.

We're working on it. The RA4x00 do things normal arrays don't or so. I'm not
yet familiar enough with this to know exactly what is needed to beat this to
work again.
>3. Aeh.. use... 2.4, use... other OS?
The 2.4 might work. And I might have some patches for you to make it a bit
less broken. But don't expect too much from it.

It was not really working, at least not when I (remotely via IRC) tested it
last time (some month ago).
