The MTRR code that's left cleans up any stale settings left behind by
a previous (crashed) X server. That's something that libpciaccess
doesn't do. Not sure how important that code actually is. I'd expect
any settings that are left behind to be right anyway. And cleaning
them potentially interferes with running a second X server.
