Do you happen to have any patches for libpciaccess to use this?

Libpciaccess (and so the latest Xorg server) hoses my PowerPC machine 
when trying to list BARs, but pciconf -b works correctly. There are 
probably endianness problems in the libpciaccess code, and it would be 
nice to just replace that mess with this interface.
