@Alex Murray: the patch seems to work which makes you the hero of the
day! :) But here are some awkward things I've come up with (using Arch
Linux - on Macbook Pro 5.1 - btw):

1) I don't know if this's related with the patch or not but alsaconf
cannot found any sound cards, but the kernel seems to recognize and load
all the necessary modules for the sound card

2) When headphones are plugged in, I've to mute and unmute the Headphone
channel a few times in order to get sound from them. I don't know why
this happens.

But all in all, the jack sense is working! :)

Bug description:
Reporting this bug for another user...

In MacBook and MacBookPro 5,1 (aluminium, late 2008) the soundcard works out of the box only with headphones, and to turn speakers on it is necessary to manually set the 6 channels. In that case, sound is heard both on headphones and right and center speaker; the left speaker doesn't work yet.

This bug is confirmed by several users, see the additional information attached.
