Linux kernel 3.3 on Dell Vostro 360

As noted in my Ubuntu 12.04 review, I have not yet found a Linux distribution that will drive the display of the Dell Vostro 360 at its native (full HD) resolution.*

The highest resolution I can get is 1280×1024.* Distributions with older kernels give me that resolution by default. Distributions with newer kernels give me a blank or blinking display unless I boot with the “nomodeset” or “i915.modeset=0” kernel parameter,* which limits the resolution to 1280×1024.

The summary of bugs reported to the Ubuntu kernel teams's release meeting of Mar.23 included the following:

* Bug:918769 - X blink with Vostro 360 and Ubuntu Oneiric and Precise
  * This was a known eDP bug for this particular SKU and vendor opted to ship anyway (supporting VGA only). Should be fixed in 3.3 where there was a big eDP rewrite. 12.10 should be more reasonable for a certification target.

Accordingly, I downloaded OpenSUSE 12.2 Milestone 2, which has kernel 3.3 RC6, to see if it solves the problem. It doesn't; I get either a blank screen or a maximum resolution of 1280×1024.* And I observed that behavior both before and after upgrading to the latest BIOS.
