Sure. Once I do the necessary mknods then the sound system works fine.
The modules loaded are as I would expect. However I do not know if they
are loading early enough for device file creation.

What is udev. Is it something to do with USB? If so, I should have
pointed out that my sound cards are PCI devices.

I have seen that stuff under /dev/.static/dev. However, from the name
(.static) and the ownership and permision of /dev/.static (drwx------,
root, root) I am assuming that these device files are not meant to be
used by user programs.
