Without swap, and paging from a solid state device, by far the highest priority is minimising the amount of ram that the kernel takes up, so I guess 2.0 will be better.

Not really. The swapin code is closely related to demand loading, as you note. The swapout code is _very_ closely related to the mechanisms for evicting unused pages of mapped files. There's not much to be gained from removing swapping.
