And that's the point: most of those still running i586 distributions do run them on 64-bit capable hardware - because they believe

It's not about belief, I can easily prove (b) to you. I don't care about (a) and (c).
OK, I'm pretty sure does consume _less_ memory. However, I seriously doubt you can prove to me the difference is (except for artificially crafted examples) big enough to outweigh the drawbacks of i586.
Nothing artificial about it - in production, I can run many more postfix instances on 32bit than on 64bit. I have been doing this for more than ten years. In this environment, I haven't noticed any drawbacks of i586, but please do enlighten me.
Per, I'm very curious if a 64-bit kernel with primarily a 32-bit userspace would get you similar ram usage.
From what I can tell, all the 32-bit ugliness, etc is confined to the kernel.
It seems reasonable for opensuse to create a hybrid 64-bit kernel / 32-bit userspace release.
From my perspective that seems like it would have very similar ram usage characteristics, but eliminate having the kernel having artificial memory constraints.
