The option is called "MergedFB", not "MergeFB".  If you want to use it,
you need only one screen section, not two.  If you use MergedFB, you
have specify the relative position of the two monitors as an option
in the Device section, and not within the ServerLayout section.

Take a look at my working xorg.conf that I use on my T42 (Radeon 7500):

Also, the radeon(4x) manual page is useful.

I once asked an older coworker and Solaris guru what happened with the
Unix-haters list. He told me that it stopped being quite so funny once Wind=
ows
NT came along.
