I guess I'm having a couple of problems..

This is OK.

I'm using gdm (default config), but /dev/dsp, /dev/audio and don't 
give me perms, I guess this is a problem:

crw-rw----+ 1 root root 14, 3 2007-12-12 20:14 /dev/dsp

Right -- I''m using XFCE so I think I'm hosed.

I guess  in the xfce rpms should start up something like this in their 
init scripts (but don't).

I wonder if there could have been some Conflicts: or other magic in 
the RPMs that would prevent making pulseaudio default if the user has 
a setup which is known not to work.
