Last known good: 3.4.4 First bad: 3.5.0
When booting 3.5.0 resolution (in console, and after in KDE) is set to 1024x768 (60Hz). In 3.4.4 was correct: 1440x900 (60Hz).
Can you please attach the output of xrandr --verbose for both kernels? Also, please boot with drm.debug=0xe added to your kernel cmdline and grab the dmesg (again for both kernels).
Thanks for the ansfer.
Here xrandr and dmesg outputs for 3.4.4 and 3.5.0
Can you please test this quick hack:
