	FTR: this bug also manifests itself with the newer
	linux-image-3.2.0-4-amd64 package (as of 3.2.32-1) and
	A8-3870-integrated Radeon HD 6550D graphics.  (Or should I try
	the version currently in Sid?)

	Strangely enough, I don't seem to recall for the recent kernels
	to misbehave on Radeon HD 6450: the ‘radeon’ module seems to
	refrain from enabling KMS there unless firmware can be found.

	FWIW, having the “pure” Debian GNU/Linux (as in: Debian main)
	fail in such a way seems like quite an issue.  Thus, I still
	hope that this issue could be dealt with before release.  TIA.
