Thank's Wei (I hope that's your first name.. I have a friend named
Wei, so I'm guessing.. my apologies if I'm wrong) :D

I'm fairly unfamiliar with Debian/Ubuntu, and even more unfamiliar
with launchpad.. BUT, I think I figured out which pieces I need for
each. I filtered on precise and pulled out the tarballs (kernel,
pulseaudio and alsalib) and when needed, used the debian/patches to
apply to the sources. I'm rebuilding my rootfs now, but I won't be
able to test it until later tonight.

I also found out what I was doing wrong on the debugging symbols, but
I don't know if it's any more helpful:

Hopefully the sources I'm using now will work anyway..

Thanks again to all for your help!
