Comment # 4 on bug 1105282 from Andreas F�rber

Matthias/Yousaf, please take a look at why vc4 is pulling in snd_pcm without
dracut noticing. Understanding that would be the first step to figuring out who
can fix in which way.

In general I would prefer a solution that does not require us to maintain a
hardcoded list of modules to include in the initrd.
Not sure whether the efifb rollback Alex suggested is viable - vc4 may need to
error out early with -EPROBE_DEFER before touching the screen for that to work.
