Ok, good to know.

A similar problem has been reported in gentoo as well [1]. Fedora
reverted partially the pci domain patch[2] from Xserver because of other
problems, but I don't think it will be enough here since
linuxDomainSupport() seems to return TRUE on sparc.

There's an upstream bug about all this pci domain mess[3] which is
supposed to be fixed before Xorg 7.3 is out. But I don't see any obvious
solution. I wonder whether we could just set is26 to 0 on all
architecture so that the server does not try any ioctl on
/sys/pci/.../config files and reverts to /proc instead as it did in
Xserver 1.1. It should work on sparc and x86 at least. However, I don't
know about other architectures. Maybe some of them were broken in 1.1
and got fixed by this pci domain change.
