Bug#627020: qa.debian.org: With update of kernel 2.6.38-2, xserver-xorg-core 2:1.10.1-2, fglrx no longer works (11-4, 11-5)

[Kevin Vargo <vargok@yahoo.com>]

Package: qa.debian.org
Severity: important

After upgrading (yesterday, 5/15) to 2.6.38-2, xserver-xorg-core 2:1.10.1-2,
fglrx no longer works.  X reports only "No protocol specified."  I've tried
the packaged fglrx (11-4-2), direct installer from ati.com of 11-4 and
11-5(DKMS fails due to kernel lock change).
Also tried reverting to 2.6.32-5 kernel, un/reinstalling driver each time.
Results are the same: blank/black screen, "No protocol specified."

I've got a Radeon HD 4250; radeon module hard-locks the display (can still
ssh in and reboot, but that's about it).  I.e., 'radeon' driver isn't an option.

I know fglrx is binary/non-free, but would appreciate any work-arounds.
