I finally fixed the problem with booting to the new kernel. It turns
out that merely renaming the /etc/modprobe.d/blacklist-nouveau file
that the nVidia installation created was not enough. I even added a #
to the line inside the file, but something was still accessing it.
Finally I nuked it completely. 

I was booted to the new kernel and X would not start, but Ctrl-Alt-F2
would get me to a command line. Using startx and reading the error
messages is what finally clued me to the fact that you must completely
nuke the blacklist file.

And even then X wouldn't start. It complained that it couldn't find any
screens. But it also said it was using xorg.conf, even though I had
renamed the one created by nVidia. I discovered that something had
created a new one. It was clean and simple and said to use the nouveau
driver. Nevertheless, I knew the nouveau driver doesn't need am
xorg.conf file, so I renamed it. Thereafter X started.

Now I can go back to the university and play with xrandr. That will
have to wait until Monday, though. Meantime I can read up on xrandr so
that hopefully I can get it to work.
