Xorg 1.5.1 SEGV on Solaris 10

I haven't needed any special options for libpciaccess on Solaris Nevada, though
I have made a number of fixes along the way that are in the libpciaccess 0.10.4
release (and a couple more minor ones in the latest git not yet released).
I've also had to finish the transition of the Xorg PCI code for Solaris to being
pure libpciaccess, without the old direct PCI accessing code - those commits are
only in the master branch so far - the set I've pulled into the 1.5.3 builds I'm
working on packaging for OpenSolaris is (I think this includes all the
interdependencies, but haven't verified just this set - our build includes a
bunch more patches for other changes, not all of which I've pushed upstream
yet):

Subject: [PATCH] Use bsd_pci stub routines on Solaris too, since we use
pciaccess for real work
I've not tried any of this on Solaris 10 though.
