Hi Vincent.

It looks like your updates have updated the kernel to 2.6.28 since you 
installed the snapshot of the alsa driver, as your alsa-info.sh output shows 
alsa driver 1.0.18rc3. You will have to upgrade the alsa driver again for the 
new kernel. Alsa driver 1.0.19 is now available from the link below, so try 
that.
http://alsa-project.org/main/index.php/Main_Page

You'll also need to run the alsa-info.sh script again, so that it shows the 
info retrieved when using alsa driver 1.0.19. You only need attach the 
alsa-info.txt file, not the alsainfo folder.

I must admit to being out of my depth with your problem with the front mic. 
It's no doubt worth trying the various model options again, once you've 
installed the 1.0.19 alsa driver against the 2.6.28 kernel.

Perhaps Takashi may have a suggestion to resolve your problem.

All the best.

Nigel.
