Here's what I'd do :

* mkdir /usr.new
* umount /tmp 
* mount /dev/hda5 /usr.new
* rm -Rf /usr.new/*
* mv /usr/* /usr.new/
* umount /usr.new
* mount /dev/hda5 /usr
* rmdir /usr.new
* -> edit /etc/fstab to be
	/dev/hda1       /	....
	/dev/hda5       /usr	....
* I'm not sure if you need a reboot. Basically
	- If the system is unstable because all the files in /tmp just
	  disappeared all of a sudden, then reboot.
	- Otherwise, the system should work fine.

PS. You are right, this IS off-topic. Next time, look at the mailing lists
listed at redhat.com, linux.org, or linux.com for example. Good luck.
