Comment 11 for bug 531736

Is such configuration even used?

You do need libpciaccess for most drivers to work, right?

Still if people build kdrive or what was the name of the simplistic single-driver X servers then perhaps it makes sense. Are these around still?

I would say adding a warning for a possible issue that can be easily detected in code is better than receiving loads of bug reports but I am not a X developer or anything so take my suggestions with a grain of salt.
