I looked at your xorg.conf file from the reference you gave.  These
things are a little confusing still to me but if I were you I would
take out the second set of specs so I was sure you were using the
display and screen you have correctly specified.  I had the same
problem when I let the nvidia configure program install a setting.  My
edits were in there but the system was not using them as it was using
the second set that the nvidia driver installed without the NvAGP, for
example.

Bottom line is that if myth picks screen0 instead of screen[0] it will
do what you are saying so I would just remove the one you don't want
as a test.  Back it up first :)

Hope I don't have that backward but you can figure that out.
