intel mobile 4 series chipset mei controller

I did upgrade the i915 drivers from 2.17 that ship with Precise to 2.19 which are the most recent ones but without luck of getting anything to display.

When booting with the flags, the external monitor works fine too, but can only do 1024x768 and can't do anything else than mirroring the laptop display. When not setting any of the above boot flags and I plug in an external monitor, the external monitor works fine. Unfortunately, this turns off KMS and my current maximum resolution on the laptop screen is fixed to 1024x768 instead of its real capability. I'd rather not turn ACPI off because I like my fans spinning and nomodeset is a bit overkill, so for now I'm booting with i915.modeset=0. To get anything on to the display after the splash screen I have to boot either with Specifically, the laptop screen goes black and stays black after the splash graphic when booting both from USB key and from harddrive.

I've got troubles getting the i915 drivers to work correctly on my laptop (HP Pavilion DM4 2101ea).
