A better way to describe that is that it doesn't consume the lanes of 
slot 1 like a pci-e audio device would, right? so you'd have slot 2 as 
x16 vs x8 with a pci-e card in 1? I will add that to the wiki.

Is gpp config automatic in coreboot or no? from what I can tell I have 
to change the gpp config settings in bootblock if I want different lane 
configs.
The asus manual says that you can't use all 5 pci-e slots at once, is 
that true with coreboot.

- Thanks, tim always got that 411!
