You also explained on IRC:

  Normally when you boot, the system bios initializes your video
  card by executing a routine in the video bios. That's what we call
  posting. So in your case, the non-int10 post code in the ddx needs
  to be fixed, or we need to make int10 stuff work for seconday
  cards with libpciaccess.

Any idea how long that "short term" is? 1.4.x works fine for me at
the moment, but I'd rather not build on that basis for indeterminate
