EXA support status for various drivers. To help out, take a driver that isn't started, or improve one of the patches below, or port the code from KAA or XAA. Documentation is in xorg git under xserver/xorg/hw/xfree86/doc/devel/exa-driver.txt and found in doxygen from in the exa.h header.
If you want to test, you will need at least
Option "AccelMethod" "exa"
in your card's Device section in xorg.conf. Do *not* try Load "exa" because it will fail. You may also want to enable Composite, by saying
Section "Extensions"
Option "Composite" "enable"
