Kernel 2.6.28-11-generic ships with broken "snd-ca010" Soundblaster Audigy SE Module

[Ray]

My Soundcard stopped working after a kernel update. I found out that the module itself isnt loaded anymore. By loading it manually:
sudo modprobe snd-ca0106

I get an error. Heres the output of dmesg:

Im using ubuntu 9.04 and 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i686 GNU/Linux

Edit:
I compiled the new kernel from kernel.org and it works fine. So this is definitely a bug.
