Hmm, I answerered, but apparently you didn't read it. So let's try
again.

You can't do that without having at least compiled all of X once.
There are many cross-directories dependencies that cannot be handled
in Makefiles/Imakefile. So you need to build the system from the top.

because you can't use xmkmf without any argument in the X source tree
itself. The README file I pointed to you earlier explains how to call
xmkmf inside the X source tree, but apparently you didn't read it. So
I'll re-explain it here:
You should pass 2 arguments to xmkmf: the relative path
from the current dir to the top of the source (i.e. the xc directory)
and the relative path from the top to the current directory.
So in your case it would be:
xmkmf ../../../../../.. programs/Xserver/hw/xfree86/drivers/neomagic

Globally no. individual parts of the X source tree can generally not
be recompiled alone. It's alot easier to start with a full build from
the top of the tree. Once you've built youre tree once, you can do
limited recompilations in subdirectories.
To cleanly rebuild the contents of a sub-directory use
make includes
make depend
make
And then make install.
BUT this only works if you've previously build the whole tree with
make World, because there are includes files and libraries build in
other directories that may be needed in the directory you're using.
