X doesn'r work after system update

	[Please keep me cc'd as I am not subscribed to the list.]

	I recently upgraded a system to:

FreeBSD 11.0-CURRENT #0 r263263: Mon Mar 17 15:09:18 EDT 2014  amd64

	This machine uses an on-board ATI HD 3300 (R780D, according to pciconf).
	Suddenly X doesn't start, using either xdm or startx.
	The applicable line in the Xorg log seems to be:

[ 19897.547] (EE) RADEON(0): Kernel modesetting setup failed

	and things slither downhill from there.
	I have googled this and found other occurances, but none that presented 
either a clear cause or a clear solution.
	(The complete log and my xorg.conf can be found at 
"http://users.rcn.com/roberthuff/".)
	This is probably my fault - somehow - but I just want to figure it out 
and get things back.
	Any ideas?

	Respectfully,
