Nokia does not have the willing/resources to work on many different 
graphicssystems.
Optimizing a graphics system is a lot of work, and the focus is on the opengl 
and raster graphics engine.  The natives ones (x11/mac/...) have the problem 
that they don't give consistent resuts accross platform, and requires a lot of 
maintenance.
There raster is great because it works the same on all platform, and is a 
common codebase, easier to maintain.

Maybe switching more application by default to raster is the solution. if not 
the entire desktop.  This need to be tested before.
So 99% of the user would have fast KDE.
