Bug#576229: Warn about missing firmware files

[Eduard Bloch]

Package: xserver-xorg-video-radeon
Version: 1:6.12.192-2
Severity: wishlist
Tags: patch

#include <hallo.h>

This is followup to bug #575945. I should mention the fact that I
_had_ a lot of radeon firmware files in /lib/firmware/$(uname
-r)/radeon/, therefore it was not obvious to look for firmware issues.
The firmware-linux package was suggested, sure, but its description
only talks about "modules from kernel source" and I obviously HAD them
installed.

The kernel log mentioned the missing firmware but that message was hard
to spot among other udev/framebuffer/... spam. The Xorg.0.log mentioned
a fallback to shadowfb but did not tell why, and even that thin line is
printed below tons of unrelated messages.

So, sorry, say what you want but locating the reason for the trouble is
not as simple as it may appear. Therefore, I offer the attached patch
which tries to detect a such situation and prints a more prominently
looking text block in the X log.

Regards,
Eduard.
