I compile myself my kernels from original sources.

This because "CONFIG_SMB_FS is not set".

Check the _original_ source:

$ ls -l linux-2.4.26/fs/smbfs/proc.c
-rw-r--r--    1 root     root   83490 Apr 14 15:05 linux-2.4.26/fs/smbfs/proc.c
$

Its content:

int
smb_newconn(struct smb_sb_info *server, struct smb_conn_opt *opt)
{
...
#ifndef CONFIG_SMB_UNIX
        server->opt.capabilities &= ~SMB_CAP_UNIX;
#endif
        if (server->opt.capabilities & SMB_CAP_UNIX) {
                struct inode *inode;
                VERBOSE("Using UNIX CIFS extensions\n");
                install_ops(server->ops, &smb_ops_unix);
                inode = SB_of(server)->s_root->d_inode;
                if (inode)
                        inode->i_op = &smb_dir_inode_operations_unix;
        }

I've no inten^H^H^Hformation to answer this question. ;-)
I just pointed out that you CAN achieve identical (however unwanted)
behavior of 2.4 and 2.6 smbfs implementation.
