As Benjamin pointed out this would be better discussed in another forum such as
the cairo mailing list (see http://cairographics.org/lists/). The gist of the
hardware acceleration story with cairo is currently that you need to be running
a development version of cairo and use the OpenGL backend, or alternatively
rely on the X server to use the hardware to the best extent possible.  The
speedups from using OpenGL are very dependent on the workload you pass it, and
in many cases the image surface is actually faster due to lower overheads
compared to talking to the hardware.  If you wish to contribute to development
of hardware acceleration of cairo or pixman, your best bet would be to join the
development mailing lists and optionally poke your head in the #cairo irc
channel on irc.freenode.net.

Hope that helps,

Joonas
