Hi!

I have a machine with two PCI graphic cards:
1x Radeon HD 4200
1x Radeon HD 5600

Starting X fails with the error message
"Primary device is not PCI"

Per discussion with macallen@ I implemented
pci_device_is_boot_vga() in libpciaccess
which uses a new ioctl().

Attached are three patches:

xorg_ioctl.diff  which implements the new ioctl
xorg.diff        which enable the use of pci_device_is_boot_vga()
xsrc.diff        which implements pci_device_is_boot_vga()


The three patches let me start X on said machine
and I also successfully tested them where X also
starts w/o these patches.

I updated my patches based on comments I got from different people.
I'm resending them for review again.

Jared suggested a KASSERT to make sure the device_t passed to wsdisplayio_busid_pci() is actually a PCI bus child. Otherwise it looks good to me.

have fun
Michael
