Every kernel since 2.6.33.2-41 (tested up to -78) only boots up showing one display.

This is a Dell Optiplex 760 with onboard intel graphics and a DVI and VGA port.

00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03)

When I boot one of the newer Kernels plymouth only shows on the DVI display - the VGA one is put to sleep.

This could be related to #584229

I'm attaching dmesg and Xorg.0.log for the -78 and the -41 Kernel.
