docs: fb: convert docs to ReST and rename to *.rst The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings. Also, removed the Maintained by, as requested by Geert.

=================
Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

This is a driver for a graphic framebuffer for ATI Rage128 based devices
on Intel and PPC boxes.
Advantages:
* It provides a nice large console (128 cols + 48 lines with 1024x768)
without using tiny, unreadable fonts.
* You can run XF68_FBDev on top of /dev/fb0
* Most important: boot logo :-)
Disadvantages:
* graphic mode is slower than text mode... but you should not notice
if you use same resolution as you used in textmode.
* still experimental.
How to use it?
==============
Switching modes is done using the video=aty128fb:<resolution>... modedb

You should compile in both vgacon (to boot if you remove your Rage128 from
box) and aty128fb (for graphics mode). You should not compile-in vesafb

XF68_FBDev should generally work fine, but it is non-accelerated. As of
this document, 8 and 32bpp works fine. There have been palette issues
when switching from X to console and back to X. You will have to restart
X to fix this.
Configuration
=============
You can pass kernel command line options to vesafb with
