I'm not sure whether this is really related to my problem:

No matter how they are ordered, shouldn't my soundcard still be 
accessible from xmms or rexima?

This results in my soundcard being no longer available:

<--  snip  -->

...
Unknown boot option `saa7134.index=1': ignoring
...
cannot find the slot for index 0 (range 0-0)
VIA 82xx Audio: probe of 0000:00:11.5 failed with error -12
ALSA device list:
  #0: saa7134[0] at 0xed800000 irq 18
NET: Registered protocol family 2
...

<--  snip  -->

But as said above, I don't suspect the order of the devices being the 
problem.
