Comment(by schlobinux):

 It is working properly on Fedora but not on Ubuntu, on the exact same
 hardware. I'll then tend to say it's a problem with Ubuntu. Or at least,
 this is a problem with your particular installation of Ubuntu. And yes,
 I'm sure I'm running openchrome on the NC20.
 You shouldn't even need an xorg conf, maybe trying without one could help.
 Also, the 2.6.32 kernel is not yet released, maybe you should try with
 something less bleeding edge. On the other hand, xserver 1.6.0 is old,
 maybe you should try with something newer. I don't know what else you
 might have modified on your system that might have an impact on the 2D
 acceleration performances. Running a F11 Live CD should prove 2D
 acceleration is working fine on the NC20.

 From your xorg log :
 959     (II) CHROME(0): Benchmarking video copy.  Less time is better.
 960     (--) CHROME(0): Timed   libc YUV420 copy... 26486040. Throughput:
