[ToH RC2] Missing bootloader
It seems that some people can't boot their Leopard after installing it. I'm not sure what it looks like but I assume they don't get into Darwin's Bootloader without building a bridge with the Install DVD. So rofl aka roflcopterguy found a solution for this I think
Boot into the ToH RC2 install DVD
Open Terminal from the disk
(where VOLNAME is the name of your partition for example "Leopard")
Now reboot without the disk and you should have Leopard running.
