This RAM base address has changed in Xen 4.5. I suspect you are trying 
this patch on top of Xen 4.4, right?

If so, it would be nice if you can try this patch also on Xen 4.5.

Is it possible to make QNX position independent?

If not, I would add a check that the load address is effectively part of 
the RAM and throw an error if it's not the case.
