No, I didn't tried it. I just recompiled the drivers from source
without the patches and everything is perfect. KMS does work and it's
a way faster than the fedora driver. The recompile took about 1 min
(and extra time for pulling the deps) and it's really easy. I'm
wondering if the patches make the driver so bloated. One of them is
called something like ***-drm or ***-modeset. And I thought those have
already been merged in 6.11.0.

Actually dropping all the patched makes the driver work very well.
