This seems to imply that there is a single locked instance of the VGA
legacy addressing. That isn't neccessarily the case. On some PA-RISC for
example you have multiple PCI busses hanging off the system busses.
So the arbiter needs to know about PCI. Your kernel interface seems to
but not your X one ?
A second question this leads onto is basically about the interface. I
would expect a sysfs interface to have made more sense with one node per
candidate vga device.
