That was not my point. Read it again.

The problem is that the 320x400 resolution does not have a 2:3 aspect ratio,
so half-width won't do it. (The aspect ratio is 4:5 to be exact.)

No, you don't need to do anything abnormal with the camera statement.
Just define a default 4:3 camera (ie. you don't need to specify any
'right' vector) and render at 320x400 and you'll get an image which
looks ok when viewed with your monitor set to 320x400 resolution (as
it is when the Windows startup image is shown).
