You can't mix and match like that - X remaps the phsyical memory into its own memory space - that particular address has no value expect for the X process. But that doesn't mean you can't access the memory region on your own - the easiest way to do that from user space is to figure out the address to map from the resource files in /sys/bus/pci/devices/0000\:00\:01.1/ - resource0 is the FB (no registers there), resource1 is the GP, resource2 is the DC and resource3 is the VP. Then you can map that area yourself from /dev/mem and read the registers directly.
