Yuck. sounds as broken as it can be. Hopefully nobody uses
such X servers anymore.

Then it won't work with this BIST hardware anyways - if it tries
to read config space of a device that is currently in BIST
it will just get a bus abort and no useful information.

The only point of this whole patch exercise is to avoid the bus abort
to satisfy the more strict hardware error checking on PPC64. On PCs
it really won't make any difference.
