I would make the same assumption, but that's not what happened to you. :-(

You misinterpreted or missed the "large number of sequential lines" part:
[1638.579] (II) FBDEV(0): Creating default Display subsection in Screen section
"Default Screen Section" for depth/fbbpp 24/32

FBDEV is being used. Why is the question I can't answer easily because I don't
use CentOS. OK, from your pastebin, here's why:
[1638.435] Kernel command line: BOOT_IMAGE=/vmlinuz-3.10.0-514.26.2.el7.x86_64
root=/dev/mapper/cl_ip--10--197--15--52-root ro crashkernel=auto
rd.md.uuid=84a77eb4:612c546f:bbfacc72:2944e155 rd.lvm.lv=cl_ip-10-197-15-52/root
rd.md.uuid=00e7a463:b7860ba3:0d667429:7d96fa74 rd.lvm.lv=cl_ip-10-197-15-52/swap
nomodeset rhgb quiet LANG
Your bootloader needs to have a less limiting selection made, or created, one
that at the very least lacks
nomodeset
which blocks use of modeset and nouveau drivers. rhgb and quiet prevent you from
seeing possibly helpful messages as init proceeds. They are typically not needed
by people who like to know how init is progressing. I'm not familiar with
"crashkernel". Likely that's only for a rescue stanza, not normally needed.
