I have appended a patch below that makes it compile. I can't test
if it actually works, though.

Apparently, there's no way to fetch the console video mode and font
information on 2.2.x. At least not with the ioctls in <machine/console.h>,
as far as I can tell.

This poses a problem. sysmouse delivers mouse coordinates in pixels,
so a character grid application needs to know the font size. I've
made that default to 8x16, but 2.2.x already supported loading of
8x14 and 8x8 fonts.

I don't know if sysmouse actually works on the kernel side in 2.2.x.
It might be too broken to use.
