Suggested package "firmware-linux" does not exist

xserver-xorg-video-radeon suggests to install firmware-linux, which does not exist. Bug #565482 was marked not fix, because the suggestion already exists in Debian. However this is not a bug in there, since that package does indeed exist in Debian, but not in Ubuntu. The correct package in ubuntu is linux-firmware, which combines the debian packages firmware-linux-free and firmware-linux-nonfree (firmware-linux is a metapackage that pulls in both of the real packages). linux-firmware is crucial because without the radeon microcodes, using the radeon driver would be impossible (see http://wiki.x.org/wiki/radeonBuildHowTo#Missing_firmware).

The problem hasn't manifested because many people have linux-firmware already installed due to other dependencies. However I do not believe that is a proper reason to leave the dependencies of this package broken in purpose, especially when this is trivial to fix. For example people running their own custom kernels wouldn't have the firmware package pulled in at all (and please don't go and say that only power users do that and power users don't matter).
