Hi,
I have installed debian stable lenny + backports on an eeepc 1201n. With the 2.6.30 or 2.6.32 from lenny-backport I don't have problem with sound : when I plug the headphones, speakers get off.
I have tested with 2.6.33 and when I plug headphones, speakers don't get off anymore. so I have sound in headphones and speakers.

I attach the output of alsa-info with the 2.6.32.9 and the 2.6.33 (I'm in a Uni Campus and it's quite difficult to have internet on a external laptop...so I attach them at this mail and I don't upload them on pastbin).
I have opened a bug on the kernel bugzilla (bug 15399). Should I provide anything more ?
Following the advice of Paul Menzel I did a "diff" of the sources of the 2.6.32.9 kernel and of the 2.6.33. In patch_realtek.c, we see that there is an new snd_hda_jack_detect funtion with 2 arguments. I have noticed that the second argument is "normaly" the second argument of snd_hda_codec_read. In the alc269_speaker_automute function there is this new snd_hda_jack_detect function, but the second argument is "nid". But in the old alc269_speaker_automute of the 2.6.32.9 the second argument of snd_hda_codec_read is 0x15. So I think there is perhaps a bug here...But I hesitate to modify the source...so I'm waiting the anwser of the dev.

I tested it. And with this modif in the kernel, after recompilation and reboot, my problem is headphones and speaker is gone.
