In the last Leopard beta version, Apple modified the minimal hardware specification required to perform the installation. Its moves fro; a G4 800MHz to 867MHz-baed hardware. If this decision was taken to ensure an as smooth and responsive interface as possible, it also will kick many users out of Leopard loop for only 67MHz which at the end probably did not really change much (performance wise).
We think Apple should have added a warning message stating clearly that to deliver acceptable GUI, Leopard will work best on G4-based system with a CPU clock speed equals or greater than 800MHz.
Of course, it will probably be possible to hack the installer to change specification parameters, but why making things easy when it can be difficult
