You should also redefine showpage in terms of the current
definition of showpage.  Don't base yours on systemdict. 
Do something like: 

/oldshowpage /showpage load def

/showpage
{
	oldshowpage
        90 rotate llx neg ury neg translate
} def

Some printers have a function called setpageparams that
allows you to use different paper sizes.  Will
GhostScript do that?  There are better ways in Level 2
also.

If they use initgraphics, don't use their program.  You
can redefine initgraphics as well, but yuck! 

Nearly all the important PostScript I print here gets
headers similar to the one described above (sometimes as
many as four of them) tacked on it.  That's to accommodate
different paper sizes, pasteup formats, environments,
etc.

If a program generates PostScript that won't cooperate,
they should fix their program.  Send them a letter or call
tech support and ask >them< for a way to do what you want.

I know in the generic case, that's not a solution, but
generic solutions fall apart if they try hard enough. :-)
