  Default video modes
  -------------------
  At the moment, there are two kernel command line arguments supported:
  
  mode:640x480
  mode:800x600
  	or
  mode:1024x768
  
  Full support for startup video modes (modedb) will be integrated soon.
  
  Version 1.9.9.1
  ---------------
  * Fix memory detection for 512kB case
  * 800x600 mode
  * Fixed timings
  * Hint for AXP: Use -accel false -vyres -1 when changing resolution
  
  
  Version 1.9.4.4
  ---------------
  * Preliminary Laguna support
  * Overhaul color register routines.
  * Associated with the above, console colors are now obtained from a LUT
    called 'palette' instead of from the VGA registers.  This code was
    modelled after that in atyfb and matroxfb.
  * Code cleanup, add comments.
  * Overhaul SR07 handling.
  * Bug fixes.
  
  
  Version 1.9.4.3
  ---------------
  * Correctly set default startup video mode.
  * Do not override ram size setting.  Define
    CLGEN_USE_HARDCODED_RAM_SETTINGS if you _do_ want to override the RAM
    setting.
  * Compile fixes related to new 2.3.x IORESOURCE_IO[PORT] symbol changes.
  * Use new 2.3.x resource allocation.
  * Some code cleanup.
  
  
  Version 1.9.4.2
  ---------------
  * Casting fixes.
  * Assertions no longer cause an oops on purpose.
  * Bug fixes.
  
  
  Version 1.9.4.1
  ---------------
  * Add compatibility support.  Now requires a 2.1.x, 2.2.x or 2.3.x kernel.
  
  
  Version 1.9.4
  -------------
  * Several enhancements, smaller memory footprint, a few bugfixes.
  * Requires kernel 2.3.14-pre1 or later.
  
  
  Version 1.9.3
  -------------
  * Bundled with kernel 2.3.14-pre1 or later.
