NX bit in OS X

(wiki article for reference: http://en.wikipedia.org/wiki/NX_bit)
It says in that article that OS X Intel "supports" the NX bit, but nothing about whether it's on by default.
Is it, and if not, how can I turn it on?

Thanks for helping me secure my Mac!

17" iMac 2GHz Intel Core 2 Duo 2.5GB RAM 160GB hard drive, Mac OS X (10.5.6), iPod 5th gen (with video) 30GB.

I don't think it's a user-operated switch.
