Duh... I forgot something important.

In any virtual environment there is almost always a machine/env instance 
parameter that declares what the screen size is (along with every other 
aspect of the environment, of course). I'm sure there is a (really 
easy?) way to change the screen size value virtual box, but I don't know 
what it is.

Deciding which way is more kludgy -- adjusting the virtual box 
environment, generating an xorg.conf or passing boot parameters -- is 
your own business, but I think adjusting the virtual box environment is 
the most "correct" solution; it is also the method I don't know anything 
about. (O.o)
