Well, until then, is it not possible to at least put the following 
patch in ports/x11-servers/xorg-server/files:

--- hw/xfree86/scanpci/Makefile.in.orig	2007-06-18 13:57:05.000000000 +0200
+++ hw/xfree86/scanpci/Makefile.in	2007-06-18 13:57:58.000000000 +0200

That would make a lot of people very happy. In particular those running 
amd64.
