Tom, 

Great to hear from a real live code developer.  Thanks for being able to
look into this.

Further documentation:

There appears to be at least something wrong with dvips.  I've now
discovered that it does what I want only if the size arguments to the -T
switch are integers in inches!  The following documents the problem.  It
was run on Redhat Linux box with ghostscript7.0 and dvips 5.86.

The bug.* files were created by doing:

 latex bug
 dvips -Pwww -T 11in,8in bug
 ps2pdf bug.ps

and the bug85.* files were created by doing:

 latex bug85
 dvips -Pwww -T 11in,8.5in bug85
 ps2pdf bug85.ps

The only difference being the argument of 8.5in instead of 8in.

Typing "gv bug.ps" or "gv bug.pdf" I see what I want.

Typing "gv bug85.ps" and I see the document upside down.

Typing "gv bug85.pdf" and I see the document right side up, but not wide
enough to see the full document.

Directly invoking ghostscript by typing "gs bug85.pdf" works, but I don't
think it is just a bug in gv.  Typing "gs bug85.ps" shows the document on
its side, while "gs bug.ps" shows the document as intended.

So somehow, the -T option fails to work properly if it is given a
non-integer size.
