I will put some logging there to be sure because as I see the codebase on the
mesa side I got the feeling that "rs400" is basically r420+ and even RC410 and
such belong to r300 so if this is consistent and good, then the kernel code
there can be too. Except if it is really called on my machine as then that
might be really-really a mistake then.

I will look at it later. Still testing a bit first if this way everything works
properly - also I have less time because there is good weather to work on wine
field and later there will be rainy weather to work endlessly on these. ;-)

Thanks for this guess! I really had no experience to even guess this.
Everything points in this direction though so I think this is the case.
