[arch-projects] [udev][RFC][5/5] remove custom rules to workaround old bugs

[Tom Gundersen]

In 81-arch.rules we have a section that loads modules that cannot be
auto detected. I think this is the wrong thing to do. If the kernel
cannot auto detect it, then we probably are not going to be any better
at it. Also, some of these rules might cause unwanted problems on
systems that do not need the modules. E.g., the snd-{seq,pcm}-oss
modules are known to cause problems with PulseAudio (and as PA is
getting more and more common and OSS is getting more and more
uncommon, I think it is clear that we are doing the wrong thing here).

In general, I think all the modules of this section are exactly what
rc.conf's MODULES array is for, so I suggest removing it.

It might make sense to keep a wikipage dedicated to modules that
cannot be autoloaded (cpufreq also comes to mind) and then add a note
in udev.install pointing there.

The relevant rules are below.

Thoughts?

Cheers,

Tom
