Andre or Alan should comment on this one.

Low activity on graphics toolkit AFAIK. I started a conversion of the
pieces to the RSB package
system and libjpeg is in there.  I did libjpeg to the RSB in under a day.

The Graphics Toolkit has been used on embedded ARM boards and pc386 with
Cirrus
VESA driver.

You should have to provide a frame buffer driver per the RTEMS FB interface
and then the graphics part should just work. Keyboard and pointing devices
will likely require USB support.

For now, you would build it using the shell script in the top directory.
As part two
of the project, you would convert the pieces to the RSB packaging format.
