--- Comment #48 from Richard Thier <u9vata at gmail.com> ---
Btw I saw that mesa codes handle my RC410 as one having RV350 (is_rv350 is
true), but unlike R400 family chip. I have no idea if that is right, but if the
kernel part do differently than the userland part that is clearly wrong that is
sure!

I kind of have a feeling this card is closer to R300 family than R400, but
these are the questions that I have problems answering myself :-(

In any ways. I think the wrong rXX_start function is called and r300_start
shoud have been called instead in my case originally... Now I am looking where
to fix this as it seems like an easy patch after properly finding the issue
source.

Actually if this is the case I am only lucky that this manifests itself only in
this subtle details because that means a whole minor family different code is
running for my card and it takes only luck that it works...
