Jailbreak an iPad 1 on a PowerMac G4? Is it possible to jailbreak an iPad 1 on a PowerPC?

I've tried Greenpois0n on PowerPC, but for some reason that doesn't work, so is there any other software I can use?

(iPad is running iOS 5)
Absinthe 2.0.4 has support for PowerPC. It works on iOS 5.0 - 5.1.1.
