Comment(by martin.langhoff):

 Status summary

  * openchrome-0.2.903
    * Bad: No rotation.
    * Good: Normal orientation is XAA-accelerated. Known to be stable.
  * openchrome-0.2.903, using SWRandR.
    * Bad: Slower than XAA accel (50% slower) -- may be acceptable. Burns
 battery 10% higher. Needs olpc-kbdshim workaround for wrong direction.
    * Good: Rotation works. Equally slow on all orientations.
  * openchrome-0.2.990 from jnettlet
    * Bad: Rotated modes are extremely slow. Gimp locks up system. May have
 other bugs / corner cases.
    * Good: Rotation works. Accelerated normal orientation.
  * chrome-??? from jnettlet
    * Bad: is not here yet. May have bugs and corner cases.
    * Good: Accelerated rotation using EXA (?). Multiple Xv
 surfaces(depends on kernel patch?). 3D accel(?).
