Just to be double sure. Did you reboot each time you downgraded
something? If not, downgrade all of them at one go, then reboot.

1. Now we really need a comparison between your working systems and
non-working systems, looking at the differences between hardware and
software.

Just thinking out loud:

A diff with the previous udev yields no difference in
78-sound-card.rules, only an ammendment of our system ruleset.

-# SOUND addon modules
-SUBSYSTEM=="sound", RUN+="/lib/udev/load-modules.sh snd-pcm-oss"
-SUBSYSTEM=="sound", RUN+="/lib/udev/load-modules.sh snd-seq-oss"

-# miscellaneous
-KERNEL=="rtc|rtc0", GROUP="audio", MODE="0664"

And 50-udev-default.rules.

 # sound
-SUBSYSTEM=="sound",            GROUP="audio"
+SUBSYSTEM=="sound",            GROUP="audio", \
+  OPTIONS+="static_node=snd/seq", OPTIONS+="static_node=snd/timer"

2. At this point I'd recommend using a Fedora Live medium to test if
your sound works there.

I'm still unsure whether this is an upstream or local problem. Tom
would be a better judge on this, especially regarding the 'old style'
boot messages. If it's not the kernel, not alsa, not udev, not init,
then I don't know what else it could be (RME card/PCI bus?).

You should file a bug report on our tracker if you haven't done so -
enables a wider audience to follow.
