Hi,
I think at least I should give it a try. If it is really impossible to convert, then we should talk about whether we should deprecate it in the future.
Feel free to try. I don't mind being proven wrong ;)
And I hope to treat cirrus as an test filed, it's a easier driver, so I can get into the drm kernel hacking quickly.
I'd suggest to start with bochs, I'm sure it is easier that cirrus.
cheers, Gerd
