I believe that what Marco is saying is that, while the ordering
of loading the modules may be important, as does indeed
seem to be the case here, its not up to udev to set that ordering,
it is handled entirely by the kernel. So it seems that Alsa needs
to be enhanced so either the ordering isn't required, or it has
some way to load oss pcm first.
With this in mind, could you please log a bug against ALSA and
report any bugs back here (unfortunately bugzilla doesn't play well
with the debian BTS). James Courtier-Dutton recently posted
(to another bug) about how he would like ALSA bugs handled.
