The BIOS is busted.  ACPI is supposed to enumerate all the Host-PCI bridges as 
ACPI devices with a specified _HID or _CID of "PNP0A03" and a _BBN field to 
indicate the PCI bus number of the immediate child bus.  Your pciconf shows 4 
Host-PCI bridges, but ACPI only lists 1.  I would look for a BIOS update 
and/or flame ASUS for violating the spec.  There's no standard way to figure 
out what PCI bus numbers to use for the Host-PCI bridges, which is why ACPI 
is supposed to enumerate them with appropriate _BBN methods.  Your network 
device is probably on one of the PCI busses we aren't seeing.
