Problem with both:

[mpeters at atlantis ~]$ rpm -E %dist
%dist
[mpeters at atlantis ~]$ rpm -E %fedora
%fedora
[mpeters at atlantis ~]$

It would make the spec file unbuildable on a lot of systems.
What you could do - something like

%define mod_x %(eval "if [ -f /some/file ]; then echo 1; else echo 0;
fi")

where /some/file is the xorg-x11-server-Xvfb path to a file that is
different from the <fc5 xorg-x11-Xvfb path to the file.

Then -

%if mod_x
BuildRequires: xorg-x11-server-Xvfb, xorg-x11-fonts-base
%else
BuildRequires: xorg-x11-Xvfb
%endif

-=-
I personally would just keep the spec files different.
