Default video modes

At the moment, there are two kernel command line arguments supported:

• mode:640x480
• mode:800x600
• 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.
