+Subject: [PATCH] pciaccess: make linux rom reading fallback optional
+
+On kernels which have ROM files, the boot VGA rom file
+will contain the 0xc0000 file anyways. If another card
+is missing a rom file there is no need for this.
+
+This is fallback is disabled by default, on the premise
+that distro shipping this new a pciaccess will be running
+on kernels with working rom support which is been upstream
+for a long time
