Sorry about the confusion, I'm still learning...
It indeed looks like you have the right package installed - I was wrong about that alsa-intel-hda-update-diwic-m6500-dkms should be in the modinfo path - it should just be "/lib/modules/2.6.32-24-generic/updates/dkms/snd-hda-codec.ko".
Now let me know if your sound is working :-)
