I think I understand why the code needs to be patched to add LCD 
capability to the boards that are able to use a DVI addon.

Panel is not supported for most of the chipsets, and falls back to VBE 
modesetting to try to enable it. And probably also enables the DVI 
module at the same time. Unfortunately, in your case, the VBE code is 
segfaulting...

it enables the laptop's panel

Yes, because you selected CRT+LCD in the bios, and the bios is used thru 
VBE. I guess if you only enable LCD in the bios, the VGA port will get 
disabled.

No idea on this one, sorry.
