You can use the patch at http://www.kyuzz.org/antirez/vga256fb.html
to get 360x480 in 256 colors without VESA 2.0 support.
It seems there are different patches to add this support in the
linux framebuffer, but I don't know where to get they.

I don't know how this works. Maybe all the graphic support is implemented
in the boot loader itself. I can't see how a boot loader can directly
use the linux framebuffer abstraction: the boot loader itself contains
portion of the linux kernel? Is it a "linux booting linux" hack?

You should provide more information about this boot loader.
