I think this is also what happens at boot on most systems before RAM is initialized, so maybe boot times could be faster if they took advantage of caches getting larger?

Not sure if you meant to point out something else but initramfs or ramdisks are loaded on to RAM itself which is already up and running at that point. RAM initialization is usually initiated by early boot firmware and information about the physical address map is eventually passed on to the OS kernel which later sets up paging (virtual memory).
