Hi, I'm currently running Linux on a computer-on-module board from Kontron. I recently upgraded the kernel from 2.6.33.3 to 2.6.35.4 and since that change, Xorg will not detect the LVDS parameters correctly. The LVDS actually uses the DisplayID format (http://en.wikipedia.org/wiki/DisplayID) to expose it's specification.
I've bisected this "regression" to commit: 61e57a8d72f2336faf39b5d940215cf085e01e6e in the kernel (http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=61e57a8d72f2336faf39b5d940215cf085e01e6e). I'm running x-server 1.7.1 with the intel 2.9.1 driver (full Xorg log attached). Errors are also popping up on Xorg startup: drmOpenByBusid: drmGetBusid reports pci:0000:00:02.0 (==) intel(0): Depth 24, (--) framebuffer bpp 32 (==) intel(0): RGB weight 888 (==) intel(0): Default visual is TrueColor (II) intel(0): Integrated Graphics Chipset: Intel(R) GM45 (--) intel(0): Chipset: "GM45" (II) intel(0): Output VGA1 using monitor section Monitor0 (II) intel(0): Output LVDS1 has no monitor section (II) intel(0): Output DP1 has no monitor section (II) intel(0): Output TV1 has no monitor section (EE) intel(0): Unknown EDID version 0 (II) intel(0): Output VGA1 disconnected (II) intel(0): Output LVDS1 connected (II) intel(0): Output DP1 disconnected (II) intel(0): Output TV1 disconnected (II) intel(0): Using fuzzy aspect match for initial modes (II) intel(0): Output LVDS1 using initial mode 640x480 .....

Also, is there support in the kernel for the DisplayID format?
