Booting G4 from G5 backup firewire drive

I'm trying to boot my G4 using my backup firewire drive from my G5 PowerMac, but when I boot with the option key and try and select the FW drive, it won't let me make the choice. The G4 was running OS 10.3, the G5 was running 10.4. But surely it shouldn't matter if I'm booting off the FW drive? Can anyone explain?

Power Mac G5, Mac OS X (10.4.11)
