If you have the (guest physical) address, there are some low-level QEMU functions you can call to get the real data from the VM's RAM.
In order to do this, you'd probably have to modify the cache structures to hold the full physical address in addition to the tags (which, don't take my word for it, but I believe shouldn't be that difficult).
