I added linux-pci because this appears PCI-related.

When you have only the 8-port serial card installed, it appears at
01:04.0.  When you have both cards installed, we don't see a new device,
and whatever is at 01:04.0 no longer looks like the octal UART.

Do you have these two cards?

  http://www.diamondsystems.com/products/emeraldmm8plus,
  http://www.connecttech.com/sub/Products/PC104plus_MiniPCI.asp

If so, both of those web pages mention jumpers that set the card's
PCI device ("slot") number.  My guess is that both of your cards
are set to the same number.
