If you have a root login enabled, login as root and change the mode.   
If not, reboot, add init=/bin/sh kernel boot parameter to the kernel  
line in grub.  mount -o remount,rw /; Change the mode, sync; sync;  
sync; mount -o remount,ro /; reboot (you'll probably need to hard  
reboot because the command won't work)

In the future, visudo is your friend.

Cheers,
Matt
