Patch 22 was specific to a few HP laptops with the CX20551 codec (you have the CX20549). The driver has been undergoing quite a bit of refinement over the last few months, so I'm not sure which version is in what kernels. The best thing to do is download the alsa-driver-1.0.14rc4.tar.bz2 release from alsa-project.org and use it. It is the most current for that codec.
