Adding:
options snd-hda-intel model=olpc-xo-1_5
or
options snd-hda-intel model=dell-vostro
resolves the headphone/speaker issue on my HP G60-530US Notebook with 'linux-backports-modules-alsa-lucid-generic' installed in lucid. However the internal mic no longer works afterwards. See:
http://launchpadlibrarian.net/40204100/alsa-info.txt.1oT26Rl85v
for device info.

There is still an issue with karmic on the same notebook due to 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.

Maybe https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/549289 could be a [MASTER] for Conexant CX2058x (Pebble) issues? And perhaps the 'Fix Committed' could also include karmic as well?
