  33 Default video modes
  34 -------------------
  35 At the moment, there are two kernel command line arguments supported:
  36
  37 mode:640x480
  38 mode:800x600
  39         or
  40 mode:1024x768
  41
  42 Full support for startup video modes (modedb) will be integrated soon.

  44 Version 1.9.9.1
  45 ---------------
  46 * Fix memory detection for 512kB case
  47 * 800x600 mode
  48 * Fixed timings
  49 * Hint for AXP: Use -accel false -vyres -1 when changing resolution

  51
  52 Version 1.9.4.4
  53 ---------------
  54 * Preliminary Laguna support
  55 * Overhaul color register routines.
  56 * Associated with the above, console colors are now obtained from a LUT
  57   called 'palette' instead of from the VGA registers.  This code was
  58   modeled after that in atyfb and matroxfb.
  59 * Code cleanup, add comments.
  60 * Overhaul SR07 handling.
  61 * Bug fixes.
  62
  63
  64 Version 1.9.4.3
  65 ---------------
  66 * Correctly set default startup video mode.
  67 * Do not override ram size setting.  Define
  68   CLGEN_USE_HARDCODED_RAM_SETTINGS if you _do_ want to override the RAM
  69   setting.
  70 * Compile fixes related to new 2.3.x IORESOURCE_IO[PORT] symbol changes.
  71 * Use new 2.3.x resource allocation.
  72 * Some code cleanup.
  73
  74
  75 Version 1.9.4.2
  76 ---------------
  77 * Casting fixes.
  78 * Assertions no longer cause an oops on purpose.
  79 * Bug fixes.
  80
  81
  82 Version 1.9.4.1

  84 * Add compatibility support.  Now requires a 2.1.x, 2.2.x or 2.3.x kernel.
  85
  86
  87 Version 1.9.4
  88 -------------
  89 * Several enhancements, smaller memory footprint, a few bugfixes.
  90 * Requires kernel 2.3.14-pre1 or later.
  91
  92
