Bug#624549: bug in radeon driver module of linux 2.6.38 (since 2.6.35)



Hi together,

does someone know if this patch has been applied already to
linux-image-2.6.38-bpo.2-amd64 (2.6.38-3~bpo60+1)?
I installed this image yesterday and had the idea to test the
drm.edid_strict=0 parameter on it today. - It works like a charm. ;)
Dunno why my patch didn't work... (But I don't have the time nor the
mood to track this down atm.)

Nevertheless: Thank you for trying to help me. - And sorry for
bugreporting this twice and not cc-ing the last mail. Reason for the
first was that I never used reportbug on this machine before and
therefore had no .reportbugrc on it which caused in a nonexistent mail
address due to some circumstances.

Best regards,
Martin
