I cannot reproduce this.  In fact,

	su root -c date > /tmp/date

hangs waiting for input.

	orion % su root -c date > /tmp/date 
	^C
	su: Sorry
	orion % less /tmp/date 
	Password:
	orion % 

Also, you appear to be running an unpatched version of FreeBSD 8.0,
subject to the rtld exploit (among a few others).  I'd suggest upgrading.

For what it's worth:
orion % uname -a
FreeBSD orion 8.0-STABLE FreeBSD 8.0-STABLE #20 r202187: Wed Jan 13
11:51:15 EST 2010     root at orion:/usr/obj/usr/src/sys/ORION  amd64
