gfxpayload and the multiboot2 header

[Seth Goldberg]

Hi,

  It looks like currently, when a framebuffer tag exists in the multiboot2 
header of a mb2 kernel, that resolution is used even when gfxpayload has a 
different resolution.  I think gfxpayload set to a value other than auto 
should override the value of this tag, as it will give consumers of multiboot2 
kernels the ability to override the framebuffer mode.  What do yall think?
