Yes and no. The code is provided for the dvips driver, to make 
Postscript out of DVI. However, there are other drivers around that take 
dvips-intended DVIs and displays them. This includes dvipng and xdvi.

I could arrange for dvipng to include the correct incanatation to make 
this work, but that would not fix xdvi's problem. I think it is better 
to fix this closer to the source.
