Fedora can't detect PCI devices

[Brian C. Huffman]

  I just installed a new motherboard and memory in a machine that was 
previously working well.  Unfortunately now the machine won't detect any 
of the PCI cards that are installed.  The PCI-Express Video card is the 
exception - that's working fine.

The motherboard in question is an Intel DP43BF.  I have 3 PCI cards: a 
PVR250, Maudio Delta DiO, and Fusion HD DVB card.  They don't show up in 
messages or in lspci -v

Anyone have any suggestions?  I'd rather not return the board, but I've 
tried various kernel options to no avail.  :-(

Thanks,
Brian
