Dave Airlie bisected the regression and it was duly reverted. That revert
is available in ickle/drm-intel-fixes, airlied/drm-fixes and linus/master:

commit 3cf2efb1a7c68d55d60dcb2ed9609e1a2fc25952
Author: Chris Wilson <chris@...is-wilson.co.uk>
Date:   Mon Nov 29 10:09:55 2010 +0000

    Revert "drm/i915/dp: use VBT provided eDP params if available"
    
    This reverts commit 869184a675662bddcdf76c5b95665272facff2b8.
    
    This is required for the Sony Vaio Jesse was working on at the time, but
    breaks most other eDP machines - machines that were working in earlier
    kernels.

Can you test whether this is sufficient for you as well?
