There is nothing wrong with using X11 at runlevel 3. The only thing
that can't be present is a display manager (KDM, XDM, GDM etc). If
it is, it is wrong, and doesn't comply with the unix standard (don't
remember exactly which, but I studied it when working for Conectiva).

The standard is there. If a distro chooses not to follow it,
you can be very sure it will have acceptance problems.

When I have time later today (or tomorrow), I'll give out the
standard I'm mentoning and will give you a proper reference.
Sorry I can't provide it from the top of my head.
