* Changed MatrixOrbital driver to support the traditional -t option

(for type: 20x2, 20x4, 20x6) etc.

* Fixed bug that appeared when using a size larger than 80 characters
  (20x4): framebuffer was allocated before size was known!

Drivers should NOT look for framebuffer to be allocated before they
start - but 80 characters are there anyway (for now).
