Yes, but I`m afraid that I don`t fully understand why do you need this
when pure hotplug mechanism is available, aside may be nice memory
stats from balloon and easy-to-use deflation. Just populate a couple
of static dimms with small enough 'base' e820 memory and use balloon
on this setup, you`ll get the reserved memory footprint as small as it
would be in setup with equal overall amount of memory populated via
BIOS. For example, you may use -m 128 ... {handful amount of memory
placed in memory slots} setup to achieve the thing you want.
