Apple doesn't support anything less than 867 MHz, not 800, but it's technically
doable.

As Richard Klein noted, you don't need to spend money on those upgrades. You
can use the hacks described at

Leopard on my G4, 450 MP. The hacks either change the processor speed
information within the installer or changes the information that's stored on
themachine to 867 or higher so that the installer doesn't balk.
