Jerry, the KMS defaults are set in the kernel, not the DDX driver.
With 2.6.32-20 KMS was on by default, and with 2.6.32-21 it was turned
off on i830, i845, and i855.

One complicating factor is that xserver-xorg-video-intel (the DDX
driver) at version 2.9.1-3ubuntu3 and earlier included a file that
would override the kernel default. Therefore, with 3ubuntu3 and
earlier, KMS would be on by default for any kernel, while 3ubuntu4 and
later will let the kernel decide.
