I think I found the issue on my karmic version... the Ubuntu version of
alsa-base for karmic is 1.0.20+dsfg-1ubuntu5 and does not include code for:

Conexant 5066
=============
  laptop	Basic Laptop config (default)
  dell-laptop	Dell laptops
  olpc-xo-1_5	OLPC XO 1.5

It only has info for:
Conexant 5045
Conexant 5047
Conexant 5051

Conexant 5066 is necessary for "CX20582 (Pebble)" and "CX20583 (Pebble
HSF)" - mine is a CX20583 ("snd-hda-codec-id:14f15067"). See:

http://package-import.ubuntu.com/diffs/alsa-driver
Note that this is for 1.0.21 and 1.0.22.1. 1.0.21 is missing from the
releases:
https://launchpad.net/ubuntu/+source/alsa-driver
They went from 1.0.20 (karmic) directly to 1.0.22 (lucid).

[ALSA: hda - Make Dell Vostro 1015n mic and speaker switching work]
Einar Rünkaru [Mon, 23 Nov 2009 20:23:49 +0000 (22:23 +0200)]
Dell Vostro 1015n uses Conexant CX20583-10Z (0x14f1:5067). Patch is
based on "olpc-xo-1_5" branch. Dell uses digital mic.

Out of curiosity, on lucid (alsa-base 1.0.22.1+dfsg-0ubuntu3) on my HP
G60-530US Noteboot I changed my 'snd-hda-intel model="olpc-xo-1_5"' to
'snd-hda-intel model=olpc-xo-1_5' - no quote marks (")  & rebooted.
Works. So the quote marks are not required. (see:
/usr/share/doc/alsa-base/driver/HD-Audio-Models.txt).
