[RFC] Drop Non-smp PowerPC Kernel Flavor

The only Apple PowerPC machines that can use the 64-bit image are the G5's (but I believe they could also use the standard SMP one).
Honestly, I don't think we can really drop any of the kernels. Any dual processor machine is going to use the SMP kernel (and there's a lot of dual processor G4's out there...), and any single processor machine needs the non-smp kernel, right? So, wouldn't dropping any of them mean dropping support one of following: single processor machines, SMP support, or 64-bit support.
I guess if you HAD to get rid of one, I'd argue for the 64 bit one. As I stated, only the G5's can use the 64 bit kernel...

Adding lubuntu-users and Julien Lavergne to the discussion to get their
feedback regarding the impact on Lubuntu users.
As Micah noted, Xubuntu stopped producing PowerPC images due to a lack
