 That explains the faulty permissions; since no filesystem was mounted
 on the (empty) directory /dev/shm it had the default 755 root.root.

 The fstab entry is perfectly fine.

 You (or the debian testing release) seem to have screwed up some
 /etc files somewhat. As said, Mandrake has the mounting of devpts
 in rc.sysinit, but I guess you could add that to fstab as well.
