Hmm, could you try this: https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules - I know there has been a rewrite of the internal mic handling lately, perhaps that would help?
Unfortunately those changes won't reach natty, so an option could be to try to disable 'Internal Mic' in the hope that it would turn what is now 'Internal Mic 1' into 'Internal Mic'.
