 We don't have this problem with OpenGL on our Sun Ultra10s with Creator3D and
Elite3D graphics cards.  Who makes the Solid Impact graphics boards ?  Who
makes the X server and OpenGL for Solaris that accelerates them ?

If you use Sun graphics hardware and Sun OpenGL you can test your 
configuration by running
/usr/openwin/demo/GL/ogl_install_check

You can configure the Sun X server to have the default visual be a 24 bit
deep TrueColor visual.  This involves copying /usr/dt/config/Xservers to
/etc/dt/config/Xservers, modifying the parameters to the Xserver to read
something like
   :0   Local local_uid at console root /usr/openwin/bin/Xsun :0 -nobanner -dev /dev/fb defclass TrueColor defdepth 24
and restarting the X server (reboot).

Mesa is easy to try, but it is not hardware accelerated at the moment.
