You are correct.  There is no need for a framebuffer height.  I just
checked the assembly code and it doesn't use the parameter anywhere.
About the only thing it would be useful for is to check that the user
wasn't specifing a starting address for the display that would end up
with the video controller going past the end of the frame buffer.  I'm
open for discussion as to whether we need to protect someone from that,
or just document that if you go past the defined frame buffer, you get
garbage data.

Garbage is not a problem.  You program the GPU wrong, it does
something wrong, programmer's fault.

We're not talking about end-user apps here.  Drivers are often
difficult to write, and the people writing them are smart.
