Small video howing how KMS&DRI2 works with old mobility radeon 9200. System is Ubuntu Karmic Koala development version. I have tweaked it a bit to install the latest video card drivers that are still under heavy development.
I used experiemental KMS/DRI2 version from git. The code is now included in latest 2.6.31+ kernels in stagging and mesa 7.6+. Ubuntu has combiled this stagging driver by default but you can enbable it by passing modeset=1 ffor radeon driver. That means from grub "radeon.modeset=1" or /etc/modprobe.d/radeon.conf (new file) with "option radeon modeset=1".
Too bad there is hardware bug in most of AGP cards that causes bad image corruption unless download from screen is disabled from exa accerlation (man exa for details just in case you get the corruption too)
DFS would give nice performance boost for GNOME and wine but image corruption is horrible to be useable.
