Sorry to come in late on this discussion, but...

As someone has already pointed out, there is no problem with the use  
of geometry here, it is just that you're not using the most convenient  
coordinates for your pspicture environment - namely, the second graph  
has points with negative y, and they are outside the frame you chose  
for your pspicture environment.

A most useful pstricks command that nobody mentioned is \psgrid
Just include it inside your pspicture:

   and will see that the picture DOES start at the top of the page.  
Also, you get a clearer notion of where your graphs lie in the  
coordinate plane.

Also, and although pdftricks does come in handy on occasion, this  
seems clearly one case where you are much better off by running
latex+dvips+ps2pdf, as you were doing.
