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).
