Black screen upon resume from RAM (existing posts haven't helped)

So where do I begin? My buddy has a Dell inspiron N5010 and I've been given ssh access to his machine. He's been using the catalyst-total package with an [Mobility Radeon HD 5430/5450/5470]. I have tried several workarounds including vga=0 in the kernel line, Option "EXAPixmaps" "off" in /etc/X11/xorg.conf. I already have an xorg.conf file generated first by X -configure and then modified by aticonfig --initial. The xorg.conf can be read at http://pastebin.com/XH49t1w3 and grub.cfg(I know editing grub.cfg is pointless) at http://pastebin.com/5L33sKmq , /etc/default/grub at http://pastebin.com/npsnpUXX and handler.sh from acpid at http://pastebin.com/0hjeB0up and additionally modprobe.conf(fglrx seems to run without adding it to this file) http://pastebin.com/nLGBEFCv . Any help would be greatly appreciated. Sorry for the long message. Thank you.

If you'd rather I post the output here just let me know. Figured I would make this nice and clean to save space and be nicer on the eyes.

In /etc/default/grub do the following changes (lines 4 & 5):

...
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"
GRUB_CMDLINE_LINUX=""
...

then recreate grub.cfg.

I'm having the same issue in a Compaq CQ61 with a Nvidia g103M. I've tried a lot of workarounds, pm-suspend, systemctl supend... but no luck.

I think it's a kernel problem because it used to work fine in Lubuntu 12.04 (I'm new to Arch), but it stopped working on Lubuntu 12.10

Did

sudo grub-mkconfig -o /boot/grub/grub.cfg after setting GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"

Still no difference. After 3 days I'm starting to wonder if it's unsolveable but I just can't believe that yet.
The only thing that remotely works is

sudo pm-suspend

if it is run manually but suspending from the Xfce4 menu gives a black screen upon resume. Maybe it's Xfce4?

EDIT: Apparently pm-suspend isn't working anymore either.

Adding the

acpi_backlight=vendor

kernel parameter helped me solve my resume problems, you might give it a try. And do a forum search for "acpi_osi", some people found that to be quite helpful in the past, too.

FYI I'm suspending with

systemctl suspend
