I also tried merging sound-2.6/master with Linus's tree, but this also did not help.
It's really strange. Are you sure that this is the kernel you modified properly? Before further debugging, check two things:
Run "git log sound/pci/hda/patch_realtek.c" and the first few entries, whether they come from sound git tree. For example, check the commit below is contained:

ALSA: hda - Fix volume-init for ALC259 with invalid widget caps

ALSA: hda - Create snd_hda_get_conn_index() helper function
Create snd_hda_get_conn_index() helper function for obtaining the connection index of the widget. Replaced the similar codes used in several codec-drivers with this common helper.

ALSA: hda - More volume-init fixes for ALC267 codec
More similar fixes like previous commits: handle the exceptional case like ALC267 where no volume amp is found in ADC widget but in the capsrc widget instead.
Also minor checks for avoiding possible erros: no connection-select when the pin has a single selection, and add beep verbs only when the 0x1d is used for beep.

To be even more sure, I re-synced your branch again and built a new kernel. The patch_realtek.c file being built is here: http://belegdol.fedorapeople.org/patch_realtek.c Fresh alsa-info.sh is here: http://www.alsa-project.org/db/?f=5051b2cb788b1db4273e06e98a78783dd0ec679f
- Confirm the running kernel is what you really built and installed. You can modify the suffix via $CONFIG_LOCALVERSION in .config file. Name it uniquely, rebuild, re-install and reboot. The new suffix should appear in the output of "uname -r".
belegdol4 is the suffix I added: $ uname -r 3.0-0.rc5.git0.1.belegdol4.fc15.x86_64
- Once when these are correct, check /proc/asound/card0/codec#0: the widget NID 0x02 should contain "Speaker Playback Volume" instead of "Headphone Playback Volume" with the latest driver.
Node 0x02 [Audio Output] wcaps 0x41d: Stereo Amp-Out Control: name="Headphone Playback Volume", index=0, device=0
Perhaps I need to specify a correct model to enable this code?
