Default SLI not working, X log says "Trouble accessing PCI Config Space"

I can't seem to get SLI working on my machine under Linux. It works fine with Windows. I have 2 GeForce GTX 560 Ti (EVGA) cards, with the cable between them.

Here is the excerpt from my Xorg.0.log:
Code:
[    30.267] (EE) NVIDIA(0): Failed to find a valid SLI configuration.
[    30.267] (EE) NVIDIA(0): Invalid SLI configuration 1 of 1:

[    30.267] (EE) NVIDIA(0):     2) NVIDIA GPU at PCI:4:0:0
[    30.267] (EE) NVIDIA(0): Errors:

[    30.267] (EE) NVIDIA(0): Only one GPU will be used for this X screen.
I have MMCONFIG disabled in my kernel. I am using a ASUS Sabertooth X58 motherboard with an ASUS Xonar D2X audio card and a PCI-E Intel gigabit network card (I am not a fan of Realtek). I have attached nvidia-bug-report.log.gz, I am running Gentoo Linux with the latest Nvidia driver (270.18) and xorg server 1.9.5. My kernel is 2.6.38.1, manually compiled.
