Sorry, if stupid question, but can this feature kick in automatically once
you have more than X MB amount of memory available, going back to default
memory-conserving "slow" mode if not? I cannot imagine that would take too
much effort/code to implement.

Ian, let's not forget that there are lot of VM systems out there these
days. If you run very narrow functionality image but your app needs to run
zillion of them you might want to dial down VM memory size to a bare
minimum. Still those VM system often use just the regular i386 loader bits.
So, yes, it's possible that some people might actually run amd64 or i386
kernels on very small RAM footprints even today.
