OK, I found the issue. One of the things I did was run GRUB2's
startupmanager and set the default boot option. While I was in there,
I also told it to show the boot splash and changed the resolution to
1024 x 768. Apparently, it did not like that. I booted the system to
a bank screen then telnetted in from another machine and removed the
contents of the GRUB_CMDLINE_LINUX_DEFAULT line. Of course I then ran
update-grub and rebooted. Viola! Now it boots normally.
