Double-check that you're really building current Git master, and that your self-built radeonsi_dri.so is getting picked up.
You are probably right, but for personal reasons I won't continue testing things for this bug. I hope some of other affected users step up and continue the tests.
I will remain subscribed to the bug so I can grant the bounty if someone gets to fix it.
