How to mount a partition as root and make it world read-write?

[VJ]

Hi,
    I read man mount and tried various options but could not do what I need.
I want to mount /dev/hdh3 as /tmp. /dev/hdh3 is ext2 formatted partition.
Also I want to make it have permissions of 777 so that all programs run by
all users and daemons (under any login) can access it. Kindly tell me what
options will go into fstab.
