 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 ?
