It isn't now but its about to be, I hope you have lots of time because
I'm going to have
to break it horribly and I've no hardware to test what it ends up doing on.
I personally think any code in the X server that isn't exercised by an
open source driver should be removed ASAP,
If this means you guys adding code to nv or nouveau to justify its
existance then so be it as long as we have a
useful test case.
