it may be worth asking the x-server team if they have received the
proposed fix and what their attitude of implementing it is so that it
lands with the kernel team. I've never had communication with the
x-server team, but have found the kernel team to be absolute stars of
the first magnitude in helping explain how to get a patch in.
