Moved over fbcon related files to the video/console directory. I also updated a few more drivers to the new api.

CONFIG_FB_STI
STI refers to the HP "Standard Text Interface" which is a set of
BIOS routines contained in a ROM chip in HP PA-RISC based machines.
Enabling this option will implement the linux framebuffer device and
an fbcon color text console using calls to the STI BIOS routines.
The HP framebuffer device is usually planar, uses a strange memory
layout, and changing the plane mask to create colored pixels
requires a call to the STI routines, so do not expect /dev/fb to
actually be useful. However, it is the best we have as far as
graphics on the HP chipsets due to lack of hardware level
documentation for the various on-board HP chipsets used in these
systems. It is sufficient for basic text console functions,
including fonts.
You should probably enable this option, unless you are having
trouble getting video when booting the kernel (make sure it isn't
just that you are running the console on the serial port, though).
Really old HP boxes may not have STI, and must use the PDC BIOS
console or the IODC BIOS.
Enabling this option will implement the linux framebuffer device
using calls to the STI BIOS routines for initialisation.
If you enable this option, you will get a planar framebuffer device
/dev/fb which will work on the most common HP graphic cards of the
NGLE family, including the artist chips (in the 7xx and Bxxx series),
HCRX, HCRX24, CRX, CRX24 and VisEG series.
It is safe to enable this option, so you should probably say "Y".
CONFIG_FB_HGA
Say Y here if you have a Hercules mono graphics card.

Read the file <file:Documentation/svga.txt> for more information
about the Video mode selection support. If unsure, say N.
CONFIG_FBCON_VGA_PLANES
This low level frame buffer console driver enable the kernel to use
the 16-color planar modes of the old VGA cards where the bits of
each pixel are separated into 4 planes.
Only answer Y here if you have a (very old) VGA card that isn't VESA
2 compatible.
CONFIG_FB_VGA16
This is the frame buffer device driver for VGA 16 color graphic
cards. Say Y if you have such a card.
This code is also available as a module. If you want to compile it
as a module ( = code which can be inserted in and removed from the
running kernel whenever you want), say M here and read
<file:Documentation/modules.txt>. The module will be called
vga16fb.o.

Say Y here if you would like to use fonts other than the default
your frame buffer console usually use.
