Subject: [PROBLEM] ATI IXP - Unknown symbol -> no sound

Hello.

short:
[2.6.18] ATI IXP - Unknown symbol -> no sound

longer:
I have an ATI IXP sound card, and since kernel 2.6.17, sometimes I have no sound
when I boot.
The card dosn't appear in /proc/asound/cards

The relevant log part are given below
What is weird is that the modules are loaded, and that it doesn't happen
everytime.
I have a P4 with hyperthreading enabled (I don't know if it plays a part).
The thing is that before 2.6.17, I never had problems

If you need any information or anything, feel free to ask.

I recently had the same "undefined symbols" problem, but they don't appear in
the same order:
