Ding!  I do see this in dmesg:

hfs: write access to a jounaled filesystem is not supported, use the
force option at your own risk, mounting read-only.

So the system is mounting it read only, even though "mount" shows it
as rw and the permissions indicate rw.  Using the second fstab line
above and mounting as root:

[root at prophead ~]# mount
...
/dev/sdc3 on /media/ipod type hfsplus (rw,uid=500,gid=500,umask=000)

[root at prophead ~]# ls -ld /media/ipod
drwxrwxrwx 1 rick rick 15 Apr 14  2007 /media/ipod

[root at prophead]# ls -l /media/ipod
total 0
drwxrwxrwx 1 rick rick 2 Jan  5  2000 Calendars
drwxrwxrwx 1 rick rick 4 Jan  5  2000 Contacts
drwxrwxrwx 1 rick rick 9 Oct  7  2006 iPod_Control

I'll try turning off journaling using my Mac at home tonight and see
if that has any effect.
