Could you please show exactly what you get, ie 'ls -al' in the mount dir
and in one subdir?

The dir and file modes are faked by smbfs, based on the values you give 
it. The code looks like this

        fattr->f_mode = server->mnt->file_mode;
        if (fattr->attr & aDIR)
                fattr->f_mode = server->mnt->dir_mode;
                fattr->f_size = SMB_ST_BLKSIZE;
        /* Check the read-only flag */
        if (fattr->attr & aRONLY)
                fattr->f_mode &= ~(S_IWUSR | S_IWGRP | S_IWOTH);

It uses the values it gets at mount time, but if a file or dir has the
"dos" attribute readonly the write permission is removed. 

file_mode and dir_mode should be the values you gave. If you run
'cat /proc/mounts' on a recent kernel (2.4.18 at least) it will show you
the values of these variables. 

You should also (re-)check that the dirs and files do not have readonly
status on the server.
