I don't know how much help I can be.  Here are some code references
that may help explain.  In sys/lib/libsa/cd9660.c:

/*
 * Stand-alone ISO9660 file reading package.
 *
 * Note: This doesn't support Rock Ridge extensions, extended attributes,
 * blocksizes other than 2048 bytes, multi-extent files, etc.
 */

Perhaps you need Rock Ridge extensions to boot a "long" filename like
netbsd-NOON?

It looks to me like ls is only implemented for ufs---in
sys/arch/i386/stand/boot/boot2.c:

void
command_ls(char *arg)
{
        const char *save = default_filename;

        default_filename = "/";
        ufs_ls(arg);
        default_filename = save;
}
