I'm not one of the core qemu developers, but I have done some tweaks here 
and
there, so take this appropriately.

If QEMU RAM doesn't have this capability already, I wouldn't mess with 
trying 
to manipulate memory, I'd create a new device that you could map at some 
useful 
location and manage on your own.  Unless, of course, you are trying to 
emulate
the memory test features of some controller.
