Oh, and here is the log with page flipping enabled.
The only meaningful diffs I saw with page flipping disabled (apart that
it works) are:
-(**) RADEON(0): Option "EnablePageFlip" "true"
+(**) RADEON(0): Option "EnablePageFlip" "false"
-(**) RADEON(0): Page Flipping enabled
+(**) RADEON(0): Page Flipping disabled
-(II) RADEON(0): Damage tracking initialized for page flipping
