Yes that should be working, but all VBE clients expect the bpp to match the accumulated color bit mask.

I've sent a fix to SeaBIOS.

Looking at the code is seems that relocation is required as the "window" has a maximum pagesize of 64K, but I'm not familar with those addressing modes.

In VBE2.0 there's a linear framebuffer that does not need relocations at
all and it's the only mode supported by coreboot's SeaVGABios
implementation.

Would it be possible to add VBE2 and linear framebuffer support to
gfxboot ?

Title:
  Installer doesn't show up on some Chromebooks: "Error setting up
  gfxboot"

Bug description:
  I downloaded Ubuntu Wily 15.10, then copied into an USB drive in order to use that to install Ubuntu on my Chromebook Pixel 2.
  After selecting the drive to boot from, I only get a terminal that shows up the following lines:

  graphics initialization failed
  Error setting up gfxboot
  boot:

  Same happens with any *buntu ISO image ( I tried KDE and XFCE as well).
  At this point, I tried to download the  Debian8 ISO image and I noticed that the installer doesn't recognize the video size, too but then asks for the user to manually select a suitable video format from a list of options. >From that point on, I was able to install Debian on the chromebook.
