AHHHHH. Thank you for that comment!
I went and checked out my /var/log/XFree86.0.log
and my system was running at 32bpp when I intended 16bpp by:

	startx -- -bpp 16   which doesn't work!

According to man startx, use:

	startx -- -depth 16


I started up X and success!

display: :0.0  screen:0
direct rendering: Yes 				<--- FINALLY!
server glx vendor string: SGI
server glx version string: 1.2
