Are you positive that is the same disk that came with the computer. If it is an install disk from a different model, it won't work. That message normally means the install disk is not for that particular model of Mac.

Yes positive. In fact, Ive done this before with the exact same disks. Only thing that changed is I swapped hard drive from macbook to blackbook without formating it.

Unless Apple's gone and done something really strange on their Intel-based Macs, your ability to nuke the computer has NOTHING to do with the present contents of your HDD. In fact, you should be able to start up from the Tiger/x86 DVD without a HDD installed (though it'll probably give you a message saying you're a very silly user for trying this).
Best guess is that something somewhere has gotten changed on your motherboard. Have you done any kind of firmware updates on this Mac?
