Liav A 3bbb5734af Kernel: Don't initialize early framebuffer console if address is invalid ...

To do so, we now check that the framebuffer type is RGB so we know that
the Multiboot bootloader actually provided a valid framebuffer to work
with.

This fixes a problem I observed on my ICH7 test machine that apparently
the multiboot_framebuffer_addr was not null but there was no framebuffer
that was set up for RGB colors, and by initializing that console, there
was a memory curroption caused somewhere in the EBDA area to probably
cause a complete system lockup.
