This is a vanilla Fedora 9 kernel, I haven't done hacking on that 
portion yet, since it came up perfectly without mod on the 
driver/hardware portion of this.

I was looking over that and did do the script as it suggested, and I 
didn't see anything but the four original ports listed on first boot. 
The problem is, three of the four are showing the Lava, with the same 
port ID's, and one is my onboard. At the least it should be my onboard 
having two ports, and the Lava having the other 2 (up to 8 when I get 
that working right)

I would have to do a bit of hunting on the IRQ side to get that sorted, 
including on my hardware so I will see what I can get. Thanks for the 
suggestions so far~
