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 ?



comparing to another machine:

00:00.0 Host bridge: VIA Technologies, Inc. VT8385 [K8T800 AGP] Host Bridge (rev 01)
00:01.0 PCI bridge: VIA Technologies, Inc. VT8237 PCI bridge [K8T800/K8T890 South]

00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control

don't remember what this one is..  just one in server pool.
(possibly ASUS A7V600 per PCI subsystem IDs.)
