Add an option to skip reading the mode entries from the vbt bios tables. This change enables the use of displays where the vbt table just contains inappropriate values, but either the vesa defaults or the video=... modes do something sensible with the attached display.

Can you elaborate a bit on why this is required? Is this for a machine (like the chrome machines) that just lack a vbios? Or do we fail to parse the vbt in some way?
Pasted from Mathias’ message with the first patch iteration.

Attached is a small change to i915 that fixes a customer case that I had in my day job.
The problem happens with an embedded board that contains vbt bios tables that do not match the attached display. Using this change and the appropriate kernel boot command line they are able to use an otherwise completely unusable secondary display on that embedded board.
Please review.
Thanks,
