I know <sigh>, but we never had enough time to improve it to use
interupts :)

You probably missed to add the lcd directory to SUBDIRS in
sh/vis211/Makefile.am and to rerun the auto*-tools on the vis211
directory. 

If you are not familiar with the auto*-tools, the easiest way to run
them is to apply the bootstrap script in RTEMS toplevel directory,
i.e.
cd c/src/lib/libbsp/sh/vis211
<path>/bootstrap
cd <builddir>
./configure --enable-maintainer-mode [options]

You also should make sure to have added your driver to BSP_PIECES in
vis211/wrapup/Makefile.am.

What you describe above is *the* recipe to add a new driver to a
bsp.

> Where is it necessary to touch to setup a new driver?
In addition to setting up the building infrastructure (What I tried
to outline above), you also need to set up your driver's hardware
and on-chip infrastructure (Eg. IO-Ports, Areas, etc.), eg. in
bsp_start (bsp-startup code, cf.
libbsp/sh/vis211/startup/bspstart.c) and/or inside of your board's
startup code.

General details on how to setup drivers for RTEMS should be
described in RTEMS' manuals.

Muchas gracias (Spelling? That's almost my whole Spanish - my native
language is German ;)
