It now suspends (choosing suspend in the menu) & resumes correctly. I'm 
noting inline what I added to each file:

Added as above...

	Blacklisted only intel_agp as suggested. As as predicted below, 
intel_agp still seems to be loading. Next, I'll try his trick (below) to 
kill it.

	Then, on to find out why it doesn't suspend when closing the lid; and 
to investigate more of what I found about the Fn hotkey not working to 
suspend it either....
