Intel DP43BF MB - No PCI Devices detected

["Brian C. Huffman" <bhuffman@graze.net>]

  I have searched and found no previous posts on this topic.  Using the 
2.6.36-rc2-git3 (and many before that rev), the kernel doesn't see my 
PCI devices.  They can be seen with dmidecode but do not show up with 
lspci (and are not mentioned on boot up).

For example, here's one of the slots (shown as In Use):
Handle 0x0038, DMI type 9, 17 bytes
System Slot Information
     Designation: PCI Slot
     Type: 32-bit PCI
     Current Usage: In Use
     Length: Short
     ID: 5
     Characteristics:
         3.3 V is provided
         Opening is shared
         PME signal is supported
     Bus Address: 0000:00:1e.0


But here's the lspci:

What can I do to further troubleshoot this?
