Hi Arnaud, Gunnar, It looks like the patch applied in Debian is missing something because another workaround is to change line 41 in the patch (I think it is) to strcat(path, dirname(firmware_value)); also allows the 1.1-1 package to properly load the firmware again.
Somehow the updates patch is overriding the earlier declaration of firmware_path and it needs to be passed again. I have tried to figure out why that is here, but I do not see what is causing it. -- steev
