I haven't had much experience using 2.0, but ever since 1.2 you have been
able to use GfxBase->NormalDisplayRows and GfxBase->NormalDisplayColumns to
get the height and width. However, I have no idea if this is set correctly
when running in PAL mode on an NTSC machine. (You can also use
GfxBase->MaxDisplayRows and GfxBase->MaxDisplayColumns to get the maximum
overscan values). I don't have a 1 meg. Agnus, so I can't even check that.
