Hi Jordan,
Sorry to bother you again, but I'm totally new to this kind of stuff.
Could you tell me exactly how to do this, or give me a link of where I
can find a manual for this?
Thanks a lot for all your help, I feel that we are getting closer ;-),
Dirk

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.
