Problem installing leopard on powermac g4

Okay, I have a power mac g4 sawtooth single CPU. I purchased a leopard install disk for the cheapest I could find without realising that it wasn't supported on this machine officially (I didn't get snow leopard because I knew that it only supported intel). So I inserted the disk (without modifying) and after booting to it got a kernel panic beginning with "the correct driver could not be found for this platform powermac 3,1". I then tried the open firmware hack many times and the same problem occured. I also tried the guide at (http://forums.macrumors.com/showthread.php?t=371302) many times even with putting in the kexts that the guide told me to if I was getting kernel panics but to no avail. I then managed to borrow my freinds intel mac and installed it to my guid partitioned 16 gb flash drive, I then cloned it to my APM partitioned other hard disk using superduper! and when booting got the same issue, I then put in the relevant kexts from the working tiger install but again to no avail
any advice is appreciated,
thanks

I was afraid of that, the problem is that I spent money on the leopard install disk and as far as I am aware ios4 is not compatible with tiger
