The current implementation from Vladimir simply dumps 1 MB of memory
contents starting at the base address of the second PCI device (which
most likely is the VGA controller on Intel systems). This locks up a
number of different systems, e.g. my Ibex Peak-based T410s.
This patch documents the issue and stops dumping the graphics registers
for the -a/--all parameter.
