OSes have had this problem solved for decades; the solution is called "swap files". You could naively get any current OS working in a system with fast and slow RAM by simply creating a ramdisk on the slow memory address block and telling the OS to create a swap file there.

What operating systems handle NUMA memory through swapping? The only one I'm familiar with doesn't use a swapping design for NUMA systems, so I'm curious to learn more.
Not really the best idea for the kind of speed baselines and differences discussed here. You can use better ideas like putting GPU memory first in the fast part then the rest in the slow area. You know, like XBox Series does.
