Thought about that.
The interesting part would be, if LRU (least recently updated pages) are stored into enhanced ram memory, controlled by multiplexed ram command and clock lines. Well, that's no workaround for today's memory prices, but would provide longer usability for today's sbc into future demands. ( Keeping in mind that one is aiming for environmentally friendly development progress, also. )
Then there is no need for the soc address space being capable of addressing the additional 2-4GB?
