What is lxfb?
=================
This is a graphics framebuffer driver for AMD Geode LX based processors.
Advantages:
* No need to use AMD's VSA code (or other VESA emulation layer) in the
BIOS.
* 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...
How to use it?
==============
Switching modes is done using lxfb.mode_option=<resolution>... boot
parameter or using `fbset' program.
See Documentation/fb/modedb.txt for more information on modedb
resolutions.
X11
===
XF68_FBDev should generally work fine, but it is non-accelerated.
Configuration
=============
You can pass kernel command line options to lxfb with lxfb.<option>.
For example, lxfb.mode_option=800x600@75.
Accepted options:
mode_option - specify the video mode. Of the form
<x>x<y>[-<bpp>][@<refresh>]
vram - size of video ram (normally auto-detected)
