Sure Alex. The countdown timer is different again. It waits 2,5,10 or 20 (if I recall) seconds after you hitting the shutter button before releasing the shutter - but that's all. The Canon 350D only has 10 secs as an option, which is way too long and unconfigurable. The shutter still opens only just before the shutter curtain opens. The D80's exposure delay pre-swings the mirror up and then waits 0.4 secs until the shutter fires. The damping, as I've said before, is more subtle than a Canon's, so 0.4 secs should be enough time if your mount is halfway stable. I'm unsure as to whether or not you can tie the two functions together - i.e. have a shutter count down delay of, say, 10 seconds that lets you hit the button which starts it counting. At the conclusion of that count it'd be nice to flip the mirror via the exposure delay and have it all settle for 0.4 secs before finally opening the curtain.

Its found in Custom Menu 31 - "Exposure Delay Mode" which introduces a 0.4 sec delay to shutter-release in order to reduce camera shake (macro, telescope, microscope photography).
