Fairly simple after all, and though this sounds long it was all straightforward and logical.
It presumes you
a) have enough space available on the target machine to hold a Leopard DVD's worth plus do the upgrade
b) have a working OS install already on the target machine
1. Use CCC to create a disk image of the Leopard DVD
2. Copy /System/Installations/Packages/OSInstall.mpkg to a working dir somewhere
3. Download and install xar from <http://code.google.com/p/xar/downloads/list>
4. Unxar the .mpkg,
5. Edit the resulting Distributions file to alter the 867Mhz restriction (I picked 345Mhz minimum)
6. Delete the copied .mpkg, create a new one also called OSInstall.mpkg (containing your modified file)
7. Using Disk Utility, create a partition to hold the Leopard installer.
8. Using CCC, clone your DVD image created earlier over to the new partition
9. Copy your new OSInstall.mpkg to <new partition>/System/Installations/Packages - this overwrites the original
10. Boot into the existing OS on the unsupported Mac
11. Select your new partition as the startup disk (running the installer app will just throw an error dialog)
12. Reboot
.....and that's it. Sounds much more fiddly than it is because I made sure to include every minor step. The logical overview is just: clone the Leopard DVD to an image, fix up the OSInstall.mpkg and put the modified one on the image, write the modified image to a partition on the target machine and then reboot with the installer partition set as your start-up disk.
Haven't got time to take much of a look at it right now but from reading around the net I'm sure there'll be no problems. A few things won't be present, such as screen sharing on iChat, but all the basics work fine.
Cheers,
Ian
