64-bit user-space on G5? Never, soonish, or unknown?

[Mikael Pettersson]

We're considering buying a G5 for porting a compiler/runtime-system
project to PPC and eventually PPC64.

The question is, will Linux ever support a 64-bit user-space
on the G5? From my reading of arch/ppc and arch/ppc64, the
differences seem major so I'm not holding my breath, but perhaps
there is hope.

Or should we just treat the G5 as a faster 32-bitter?

Or should we use some other OS than Linux :-(

TIA,
