Because as you quoted, the su binary doesn't have the UID 0,
this means it's not owned by root anymore which may have bad
influence on its runtime behaviour. :-)

You have:

-r-sr-xr-x  1 rocketmouse  wheel  16880 Dec 23 18:38 /usr/bin/su

You should have:

-r-sr-xr-x  1 root  wheel  14604 2011-08-21 20:24:28 /usr/bin/su*

As I mentioned in my previous message, somehow the UID change
had some strange side effects.
