it is essential that this work. Some subsystems, ie. USB, need to allocate
memory to do IO. For them to work, small allocations must be possible.

Now, is this a real issue? Can most devices really save a device state?
This capability seems to me to be limited to memory mapped IO at best.
USB devices generally don't save and restore state but bring the device
into the state it ought to be in, not the state it was in during resumption.
