	You don't mention your graphics chip explicitly, but building
libdrm with the KMS option was enough to prevent X from starting on
a Radeon HD 3300.  ("Experimental", indeed!  :-)
	Other will be able to help more if you could post the contents
of "/var/log/Xorg.0.log" and your xorg.conf file.

	Respectfully,
