Hmm. When I run Apple System Profiler I get the following entries
AGL.framework 2.2.7 18 Dec 2002 01:23 AM OpenGL Carbon
compatibility dylib for Mac OS X
GLUT.framework 2.2.7 18 Dec 2002 01:29 AM GLUT dylib for Mac OS X
OpenGL.framework 1.2.1 18 Dec 2002 01:20 AM OpenGL 1.2.1.9.0
Does this mean my PowerBook G3 FireWire doesn't support OpenGL 1.4 or
that somehow my update to 10.2.3 didn't go quite right?
I tried LDGLite, and I didn't notice any difference. LDGLite still does
receive keyboard input.

I do not know what you mean be an offscreen command line renderer. Do
you mean that running the command will procude a graphic file without
drawing the model to the screen?
