	* Mouse pointer code added to the bogl cfb8 driver.
	* K & R parameter declarations converted to ANSI.
	* Main control loop uses select() instead of busy waiting.
	* Beginning of code to redraw screen on switching to graphics console.

	* Some minor bugs fixed.
	* Many major bugs added.
	* ChangeLog, TODO, BUGS, README, INSTALL, etc. written.
	* Probably various other things I've forgotten about now.
