Problem solved, but rather strange.
When I first booted with the previous kernel I looked at /var/log/messages
and didn't see anything useful. Today, I selected the previous kernel
from the grub screen and looked at /var/log/Xorg.0.log. The date in the
file was today, so that was from the current boot, not from the time it
failed to give the login screen.
I edited inittab to default to runlevel 3. I got the runlevel 3 login
prompt, did startx, and the GUI came up. I restored the runlevel 5
default in inittab and rebooted letting the new kernel get selected by
default. The login screen came up.
It must have had something to do with the initialization of X on the first
boot under 5.6.
Your suggestions helped.
Thanks.
