+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.
