Good question. 
Not an answer, but a comment. Default background 
colour is set by a scheme, so another solution 
to this issue is to use a scheme with the right 
background colour, which at its simplest could be a 
clone of your favourite scheme, but edited so 
that there is a line 
color background white 
For slides Svend Juul's schemes work very well.
