I've tried again without video parameter -- same outcome. I've also
applied Ville's patch "drm/i915: Read timings from the correct
transcoder in intel_crtc_mode_get()" (with teeny backport fix). It seems
this code is never called in my case though, since intel_lvds_init()
chooses to use the VBT
Here's the same issue on a more reasonable kernel. The log looks quite
different, but the end result is still a blank screen. Uploaded here:

Hi,
My setup is an embedded GM45 based board with a screen connected via 24
bit LVDS. When trying a to use a newer kernel (3.14.57) with KMS, the
screen stays blank. I'm only testing KMS so far, no X. Older, pre-KMS
versions of the kernel worked fine.
I'm hoping that a resident Intel DRM guru
