These are all in the same place as the main xy.tex files. On my system, 
for example, the xyps-l driver (for PostScript line support) is in

The xdvi driver only supports line thickness when you have PostScript 
enabled inside your xdvi (see the "XDVI Driver" section of the reference 
manual). This version of your document renders correctly for me with xdvi:

\input xy
% or just \usepackage[ps,xdvi,line,arrow]{xy}
