Intel driver, black screen on start/resume

Hello.
Using the intel driver for the intel graphics in my Travelmate C111 Arch/GDM boots up into a black screen, hitting the 'lower-brightness' hotkeys brings back the desktop. The same happens after resuming from suspend - black screen. The hotkey again works. I have written a gnome session startup script using

xbrightness -set 0
xbrightness -set 50

to automatically bring back the backlight on startup.
Is there any workaround for bringing back the backlight on suspend->resume automatically or error logs to look through, until now I was not able to find any error message (Xorg.0.log, ACPI,...).

This is the last issue on Arch/Travelmate C111, I'd really appreciate any help on this.
