Burn bootable OS-X Leopard DMG image to USB

I have a bootable Leopard DMG image that I'd like to burn to a USB stick.
I want to be able to boot off the USB stick if I need to for AHT or OS reinstall.

The DMG image is 6.8GB and the USB stick is 8GB.

Disk Utility will not let me burn to a USB - only SuperDrive (my SuperDrive is SL DVD-R (4.7GB) burner anyway).

I figure if I just mount the DMG image and then drag everything to the USB stick, the USB stick isn't going to boot.

What's the trick?

And where did you get this image from?

Does it make a difference?

It sure does.

A legal difference. Apple doesn't ship Leopard as a DMG image.
