  I downloaded the HG version, compiled against my kernel and re-loaded just
the modules ( so as not to break too much else ). I get the two microphone boost
controls ( one for playback and another for capture ) and they work. I can
record from both internal and  external microphone.

 The `Internal Mic.' bar/switch appears to do nothing

 The `Microphone" bar/switch is active and behaves as expected

 I see a couple of extra modem related controls ( Caller ID and Off-hook ) -
does that mean I can make the soft modem ( Si3054 ) work with slmodemd --alsa ???

 Still no PC speaker ....

  I tried applying the automute patch but I must have picked the wrong 
version of pci/hda/patch_analog.c because most of the patch failed. At
what stage was the patch supposed to be applied ? I did it after having
done all the steps on the devel page.
