Leopard will indeed install on a slower than 866MHz Mac. The way to do  
it is to start the TiBook in Target Mode while connected to a faster  
than 866MHz machine. Start the faster Mac with the Leopard install DVD  
inserted and select the TiBook hard drive as the installation  
destination. It will do the installation without any hesitation.

Once the installation is complete, shut down both machines and then  
restart them without the firewire connection. The TiBook will now have  
Leopard installed and you will need to set your configuration  
preferences.

This has worked on my 733MHz G4 and I have read that it also works on  
the Cube model G4s but they will run slower than a normal Leopard  
install because of the slower processor speed.

Good luck.
