There is no tmpfs in vanilla 2.4.3 kernel.

I use this start script to mount tmp/shmfs:

#!/bin/sh

[ -d /dev/shm ] || mkdir -p /dev/shm

shmfs_avail=$(grep -qci 'shmfs' /proc/filesystems || true)
tmpfs_avail=$(grep -qci 'tmpfs' /proc/filesystems || true)
devshm_mounted=$(grep -qci '/dev/shm' /proc/mounts || true)

[ $devshm_mounted = 0 ] || exit 0

if [ $shmfs_avail = 1 ]
then
        echo -ne "Mounting shmfs: "
        mount none /dev/shm -t shmfs && echo "ok."
        exit 0
fi

if [ $tmpfs_avail = 1 ]
then
        echo -ne "Mounting tmpfs: "
        mount tmpfs /dev/shm -t tmpfs && echo "ok."
fi
