Indeed - infrastructure for flipping seems to be ready:


[837858.379] (II) RADEON(0): KMS Pageflipping: enabled
[837858.379] (II) RADEON(0): SwapBuffers wait for vsync: enabled
[837858.389] (II) RADEON(0): Output HDMI-0 using monitor section Monitor1

If You believe we should do some tests with added debug outputs - I'm more than
happy to do so :-)
