I am not impling hotplug should load the OSS drivers. I agree with the
latter solution of setting up a proper modutils dependency - something
alsa-base should be doing.
However, I do have a problem with hotplug doing PCI enumeration. Certainly,
I think it is something Linux has been missing. But, indiscriminately
loading the drivers for all hardware on a computer is the wrong behavior, as
has been demonstrated by multiple people.
I'm not totally convinced the option enabling/disabling PCI enumeration is
the solution either.
Where is a Device Manager when you need it? ;-)

I have not found them fragile.
Furthermore, if they are so, then why is this being done?

No, the conclusion it draws is wrong. The entire ALSA subsystem has _not_
been loaded. It thus skips the rest of its initialization because of this
incorrect assumption.

udev is not the solution at this time. The package isn't not at a complete
state (README.Debian), the upstream software is still severely alpha
(0.023), and there are race conditions involving driver loading...
.. and let's not forget that udev currently causes another layer of
brokeness with ALSA (#240594) and LVM. (#236346 ?)
The fact is udev is not an upgrade path yet for 2.6 users. If it was, and it
is required, where are the Depends?
Scott.
