Re: Fujitsu Lifebook E751 (iGPU: HM65): distorted console with UEFI boot

Note about hw.vga.textmode: this tunable has no meaning for UEFI - first of all, there is no API to change to VGA text mode in UEFI, secondly, there may or may not be VGA (firmware) at all. We only do land in kernel with linear framebuffer mode active and all we have is information about that mode (FB address, size and color bits). In *worst* case, it is actually even possible that we only have UEFI API for boot loader and no linear framebuffer for kernel.

distorted console after kernel start means that either the kernel efifb driver does something wrong, or the console device gfx mode change did happen but the FB driver was not properly informed about the fact.
