commit bfcfdff7a00a579362eca0def5b85c1a013ef1e0
Author: Paulo Cesar Pereira de Andrade <pcpa@mandriva.com.br>
Date:   Mon Jul 28 18:45:00 2008 -0300

Convert nsc driver for libpciaccess.
    
      The driver did compile because it only had calls to undefined functions,
    but would fail at runtime due to unresolved symbols. This uses the same
    conversion used in other drivers, by using a local "pcirename.h" file.
