This change must be done in the "first" kernel, so that when kdump 
starts, it doesn't hang the machine by writing to the VGA interface, in 
the early boot code.

To make this change less intrusive, we can do it only on problematic 
hardware (G200_SE rev 42), but Thomas said it was probably not needed.
