With the aid of the advice below (thanks to all who answered!!!!), I am
nearly
there with the Apple 17" LCD monitor. The boot process remains invisible,
but
the command
/usr/sbin/fbset "1280x1024-60"
at the end of /etc/rc.d/rc.local gives me a text-only window. X does not
yet work (Xconfigurator failed; I still need to try the Xautoconf directions
at the yellowdog web page), but I at least have a working installation.
The install process allowed me to provide a 1280x1024 resolution, so
there was no need (yet) to edit the /etc/X11/XF86Config-4 Screen section.
