NetBSD has a framebuffer, but until now, it is not much used. The framebuffer can be used for showing nice fonts and resolutions in the console, to show a spashscreen while booting, etc., but there is no documentation.

The genfb(4) and wsdisplay(4) manpages are a good start with this.

Your task is to try using the framebuffer, document what you are doing and why, and report what is missing and where you have no idea how to go on.
