alsa mismatch with new kernel-image

[Jonathan Kaye <jonathan.kaye@univie.ac.at>]

Hi Debianers,
I recently did an upgrade of the sarge kernel image from 2.4.27-2 to 
2.4.27-6. All went well except for my alsa which is now out of sink. 
Running alsaconf recognises my card correctly but when it tries to 
install the card I get a mess of "unresolved symbols in /lib/modules..." 
error messages. My lsmod now looks like this:

I've searched around for some solutions but come up empty so far. Any 
help would be greatly appreciated. Note that alsa was working fine on 
the old kernel image.
Cheers,
