systeminfo + dmesg + dmesg-nopat + Xorg.0.log

Description of problem: 
Xorg crashes after resume from suspend. The system responds to sysrq+REISUB, and I was able to get crash logs (attached, + systeminfo. note that this is a dual AMD graphics system, OS: ubuntu 12.10 amd64, using LXDE + some KDE apps). This happens only when using the integrated GPU (HD 6520g). Also, mouse pointer feels more sensitive and I can see the crossfire settings in amdcccle (AFAIK, it shouldn't be there, but I'm not sure).

Steps to reproduce:
1. Activate the integrated GPU
2. reboot system / restart X
3. suspend to RAM ( "sudo pm-suspend && sleep 10 && dmesg > dmesg.txt" worked, see logs )

Actual result: 
black screen, system responds to alt + sysrq + REISUB
Expected result: 
Successful resume from suspend

I forgot to mention... it happened in 12.11beta* and before, too. I don't remember the exact moment I started noticing this.
Also, the logs are kinda old, but it's been the same, so no edit to make new logs. Anyway, if you need more info or some other help, let me know.

fglrx also fails to resume from suspend for me. I'm using an Asus NP56D with both the IGP and a discrete HD7730M. Usually I only have the integrated HD7660 in use, for battery life.

Not sure if this is the same bug - usually the laptop fails to suspend too. It sits there with the power light on; if I hold the power button it eventually suspends (and the power light blinks as expected). But yes, on resume, the display doesn't power up.

Using LXDE on Arch Linux
