Nope, that doesn't work in my case, and I don't see the reason why it should
work, but thanks. I've solved my problem partially, got acceptable solution,
simply using glamor, but forcing Option "DRI" "2". That was how I used it 1
year ago or so, but did found out that EXA works better for my use case.

Still, bug should be reported, I've tried all pageflip related options in Xorg
configuration, same thing, from what I've seen in the code of the mentioned
patch, it seems that removing:

-extern Bool
-radeon_get_pixmap_handle(PixmapPtr pixmap, uint32_t *handle);

from radeon_bo_helper.h togheter with the rest of the code broke things, I've
tried to rever those changes but got compilation errors,a nd since I'm not
programmer and not familiar with structure I assume other commits latter might
relate to this one, so it would be hard for me to find what is the problem.

It could be that added lines in exa file did something, I will try to find it
again, probably today.
