Date:           Sat Jan 22 15:18:57 UTC 2011

Modified Files:
        xsrc/external/mit/libpciaccess/dist/src: netbsd_pci.c

Log Message:
Implement pci_device_is_boot_vga() for NetBSD using new WSDISPLAYIO_GET_BUSID 
ioctl.
This lets Xorg start on machines with more than one PCI display device
instead of exiting with 'Primary device is not PCI'.

First discussed with macallan@ then public on tech-kern@ and tech-x11@.
