The original intent of this testing was going to be for an Ubuntu 8.10
vs. Ubuntu 9.04 development article, however, after seeing these Intel
performance regressions, those graphics results were then published.
It's clearly mentioned in that article that these were the results from
the stock packages of Ubuntu 8.10 and the Jaunty repo as of Dec 18.
As is stated in the article, once the various packages (kernel, X Server
1.6, et al) near a point of stability, they'll all be tested properly
and built from source in a vanilla configuration with all other
variables remaining the same.
