I'm not having any luck with this patch on my XPS M1330. I built against
Ubuntu Gutsy (2.6.22 which requires some PIT_TICK_RATE futzing in
pcsp.h) from current ALSA repo bits after Takashi applied it to HG. I
also removed Gusty l-u-m which contains a conflicting snd-hda-intel.

Audio output works fine. The only record source that appears to work is
the external microphone (front input), though it is very faint even with
mux 1 cranked to the max.

Can you describe your environment and record applications? Perhaps I'm
just missing some assumption.
