It would be best to wait for the maintainer, but if you're feeling adventurous:
(based on https://wiki.ubuntu.com/PbuilderHowto)
Open a terminal and execute the following:

1. sudo aptitude install pbuilder debootstrap devscripts
2. sudo pbuilder create --debootstrapopts --variant=buildd
3. mkdir ~/src

save the three attached patches to ~/src

4. cd ~/src
5. apt-get source linux-backports-modules-alsa-2.6.31-14-generic
6. cd linux-backports-modules-2.6.31-2.6.31/updates/alsa-driver/alsa-kernel/pci/hda/
7. patch -p4 < ~/src/conexant-rc8.patch
8. patch -p4 < ~/src/hda-jack-detect.patch
9. patch -p4 < ~/src/vostro-1015.patch
10. cd ~/src/linux-backports-modules-2.6.31-2.6.31
11. pdebuild

This will take a fairly long time.

If everything went correctly, you should now have /var/cache/pbuilder/result/linux-backports-modules-alsa-2.6.31-14-generic_2.6.31-14.16_amd64.deb (or _i386.deb or similar), which you can install with gdebi-gtk. Reboot, and you're done.
