Bug reported on the Debian BTS by Maximiliano Curia:
Using isolateDevice limits the video cards that X will touch when doing a pci
analysis. This allows to have different X servers in different video cards, that's
mostly used for multiseat. I wanted to have a Xinerama X (with two video cards)
and a secondary seat X. But isolateDevice would not allow to "isolate" two
video cards, so the Xinerama+multiseat was imposible.
The patch attached changes the xf86IsolateDevice to list of PCIids so it's
possible to have more than one isolated device per X server.

Patch to isolate multiple devices
Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future.
Tagging patch; will triage later.
