What is the cdrom? Music or Data? You can't mount a music cdrom... period. 
However, if it's a data cd, then iso9660 MUST either be build into the kernel 
or available as a module for the "auto" part of your cdrom fstab line to work 
correctly... hmmm... maybe need also "autoload" in the module loading section 
of the kernel configurator.
