I can't find any x86_64/ia32/x32 benchmarks in that article? Regardless, 
I'd agree that x32 is potentially useful on heavily resource-constrained 
interactive devices like phones. The quesiton is whether it's useful for 
any of the platforms that Fedora targets. Virtualisation is something I 
hadn't considered and it may be that there are benefits there, but I'd 
still appreciate some real figures before encouraging people to spend 
time on it.
