Multiboot non-VBE video?

[x vedejas]

I'm pretty sure this was working in GRUB 1.97, but currently I am
using GRUB 1.98 and the fields described here no longer work:

http://lists.nongnu.org/archive/html/grub-devel/2010-01/msg00121.html

The values I previously was given by GRUB were

framebuffer_width = 800
framebuffer_height = 600
framebuffer_bpp = 24
framebuffer_type = 2

Now I get, with no modification to my code:

framebuffer_width = 2400
framebuffer_height = 800
framebuffer_bpp = 88
framebuffer_type = 2

Has this "specification" changed? Was the patch only added for the
particular version that worked in the ubuntu distribution of GRUB? Is
it possible to fix this by applying some patch to 1.98?

Thanks,
