Make sure you have support for shm and tmpfs in the kernel.
(I think SHM is default but you have select
"Virtual memory filesystem support" under Filesystems/Pseudo fs)
If you have that you shouldn't have to have any entry in fstab;
the kernel automounts /dev/shm with 1777 permissions.
I've read that having fstab mount /dev/shm after the kernel has mounted
it might cause xruns.
The fstab entry, I think, is only for 2.4 kernels.
