If it helps, I just spent all of yesterday testing out different things, 
and finally broke down and rebuilt the kernel with OSS modules.  It 
seems like as in Debian, I am unable to get ALSA to work with gstreamer, 
but I may also need a patch to the source, as I also downloaded the 
ubuntu 2.6.11-1 smp kernel, and that did not produce sound in gnome with 
ALSA.  The only one that did was the 2.6.10-5 powerpc kernel that came 
on the original hoary install disks.  I wouldn't know on Debian because 
I never ran, or know if there is even, a 2.6.10 series kernel, and the 
2.6.9 one I ran I used KDE, when I switched to gnome I was already using 
a self compiled 2.6.12-rx series kernel

I have also had that problem with /dev/dsp not being there, back when I 
first ran debian and KDE, and it was suggested to me that there was a 
problem with the ALSA rc scripts not being run at the right time or 
something, or generally not working the way they were supposed to.  In 
the end I had to echo a couple of modules into /etc/modules to get that 
to work.  In my case snd and snd-powermac, (that would obviously be 
different for non-ppc people)

But to wrap this all up, I finally reached the goal of getting something 
besides esd to work with gstreamer, it's OSS, and "obsolete" but I think 
this will let me have sound in MOL where ESD wouldn't
