Think about using "LeopardAssist"

That is wrong. I've done it.

The retail release of Leopard is universal, and a copy installed on any
Mac model will boot any other Mac model which existed prior to the
release of that DVD.

Which Mac Pro model? This probably wouldn't work if you were trying to
clone the system from an Early 2008 Mac Pro, because that has a
model-specific build of Leopard, since the computer was released after
Leopard.

If it was an original Mac Pro that had been upgraded to Leopard with the
retail DVD, cloning its system should work fine.

It works for me. I've installed Leopard on an external Firewire drive
(using the APM partition scheme) from my PowerMac G4. It boots my
MacBook Pro perfectly well.

If your Mac Pro is the latest model, it won't work with a Leopard system
cloned from another computer, because that Mac Pro is newer than the
retail release of Leopard and requires its own special build.

The same would apply to a MacBook Air, or a late 2007 MacBook, if
dealing with the 10.5 retail Leopard DVD.

Apple have already released a 10.5.1 retail DVD. That DVD should be able
to support a late 2007 MacBook. When they next update the Leopard retail
DVD, that DVD should also support the MacBook Air and early 2008 Mac Pro
(and any other new models released prior to the version of Mac OS X
included on the DVD).

Have you really had Leopard working on a B&W G3 with G4 processor
upgrade (or a PowerMac G4 with PCI Graphics, for that matter)? I haven't
heard of anyone successfully getting Leopard working on a pre-AGP model.

I'd be very surprised if anyone has Leopard working on a B&W G3 which
still has a G3 processor (of any speed), since most of the code in
Leopard was built to require at least a G4 processor.

Yep. I had a FW drive set up this way within a couple days of receiving
Leopard, and I could even boot an 800 MHz PowerBook G4 from it, even
though you can't install Leopard directly on that model.
