[kinda solved] Intel HD4000 screen corruption

Question

Kernel 3.3.8 and results in screen corruptions right after "udev" finishind events. The system freezes and that's it.
Kernel LTS kind of works, but I get minor glitches when running gnome-shell (guess - 3.0.x has no Ivy Bridge support).
I did already try to recreate the initramfs via
mkinitcipio -p linux
(3.3.8, not lts) with the modules
i915
aswell as
intel_agp
(/etc/mkinitcpio.conf) specified, but neither did change anything.
Additional kernel-params
i915.modeset=1 i915.semaphores
do not change anything.
Booting with
nomodeset=1
kind of works, but I can not start a X session due to KMS/modesetting being required for the driver.
I also played around with BIOS settings enabling and disabling RC6 and render idle modes in the BIOS do have no effect either (I did not enforce/disable RC6 via kernel-options yet).
Any help is appreciated
Thanks a million

No special hw used/connected, just the motherboard+4G memory.

Tv connected via hdmi, but the same behavior observed over vga too.
