It's not, at least not on the forums.  The X11 section of the Handbook 
needs a complete rewrite.

Last I knew, --configure caused a core dump.  I don't know why, but it's 
just another reason to avoid it.

We could be dealing with multiple problems.  It's hard to tell.  The 
reason for asking about the exact hardware was to see if either or both 
of the Intel and Radeon hardware was too new to be supported, because 
then the vesa driver would be involved.

I'm not sure even those are needed.

As above, the X11 chapter needs a rewrite.

Yes.  Some people still use /etc/X11, but that breaks the separation of 
ports and base.
