Thanks for this, I havnet had much time today but I implemented the hack as
laid out in http://lists.debian.org/debian-sparc/2004/02/msg00013.html

Now lspci and scanpci do indeed show the same output again. 
XFree86 -scanpci is still empty and X does not start in multihead mode:

   Fatal server error:
      Cannot run in framebuffer mode. Please specify busIDs        
      for all framebuffer devices

But I specified them in the XF86Config-4 and each card is working fine in a
single screen layout with the data below. 

Section "Device"
        Identifier      "Creator3D"
        Driver          "sunffb"
        BusID           "SBUS:/SUNW,ffb@1e,0"
        Option          "UseFBDev"      "true"
        Option          "FBDev"         "/dev/fb0"
EndSection

Section "Device"
        Identifier      "Matrox Millenium"
        Driver          "fbdev"

        Option          "UseFBDev"      "true"
