The hard way :(  I had to edit the driver in question and recompile
ghostscript.  There isn't any other way I could find (and I had the source
anyway, as I'm using gs3+ which cannot be commercially distributed.)

There is also a file in the ghostscript libraries which specifies the sizes
of standard formats.  I have changed papersizes directly there once.

It may help, but doesn't have to.

Beats me.  I'm PostScript illiterate, however.

But I can try to play a little with tiff2ps and gs, and tell you what goes
on my installation.
