While most\nmodern devices allow relocation of such ranges, some \"Legacy\" VGA devices\nimplemented on PCI will typically have the same \"hard-decoded\" addresses as\nthey did on ISA. For more details see \"PCI Bus Binding to IEEE Std 1275-1994\nStandard for Boot (Initialization Configuration) Firmware Revision 2.1\"\nSection 7, Legacy Devices.\n\nThe Resource Access Control (RAC) module inside the X server currently does\nthe task of arbitration when more than one legacy device co-exists on the same\nmachine. But the problem happens when these devices are trying to be accessed\nby different userspace clients (e.g. two server in parallel). Their address\nassignments conflict. Therefore an arbitration scheme _outside_ of the X\nserver is needed to control the sharing of these resources.
