This problem machine is ASUS A8N-SLI Premium AMD CPU family/model/stepping: 15/35/2

The question is:

  Where are "host bridge" subsystem things in this new
  ASUS board with NVidia nForce4 ?


I see a similar scenario on a Gigabyte GA-K8NF-9 board:

00:00.0 Memory controller: nVidia Corporation CK804 Memory Controller (rev a2)
00:01.0 ISA bridge: nVidia Corporation CK804 ISA Bridge (rev a2)

Maybe it's a BIOS thing, like how some hide the SMBus interface?
