The terminal uses console.Vga as its output device. A proper terminal implementation would be using a console.Console interface as its output. However, at this point we cannot use Go interfaces as the fn pointers in the itables have not been yet initialized. The Go runtime bits that set up the itables need access to a memory allocator, a facility which is not yet provided by the kernel.
