Learned a little at:

http://www.scyld.com/pci_irq.html

So I found that I have:

  cat interrupts
            CPU0
   0:     103391          XT-PIC  timer
   1:          3          XT-PIC  i8042
   2:          0          XT-PIC  cascade
   5:      68774          XT-PIC  wcfxo, eth0
   8:          1          XT-PIC  rtc
   9:          0          XT-PIC  acpi
  10:          0          XT-PIC  Intel 82801BA-ICH2
  11:      68594          XT-PIC  uhci_hcd, wcfxo
  12:         66          XT-PIC  i8042
  14:       4174          XT-PIC  ide0
  15:        893          XT-PIC  ide1
NMI:          0
ERR:          0

I turned off the internal serials on 3&4 and the Parallel on 7, buy 
the BIOS only allows me 5,10,&11 for these PCI devices  :(

One ethernet and one FXO share 5, and the USB and the other FXO share 11

Since these are serial devices I am going to ASSUME that they will be 
serviced well enough.

Since I am not using my USB, I will put my main subnet on the 
internal ethernet and main phone on the one using irq11...
