How to solve [drm:radeon_init [radeon]] *ERROR* No UMS support in radeon module!    in redhat linux?

I watched my laptop reboot after a system update and there was an error mention that caught my attention. I issued a # dmesg | grep radeon and the results were:

 

 

[    0.000000] Command line: BOOT_IMAGE=/vmlinuz-3.10.0-327.10.1.el7.x86_64 root=/dev/mapper/centos-root ro crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet LANG=en_US.UTF-8 radeon.modeset=0 rd.driver.blacklist=radeon

[    0.000000] Kernel command line: BOOT_IMAGE=/vmlinuz-3.10.0-327.10.1.el7.x86_64 root=/dev/mapper/centos-root ro crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet LANG=en_US.UTF-8 radeon.modeset=0 rd.driver.blacklist=radeon

[    3.837187] [drm:radeon_init [radeon]] *ERROR* No UMS support in radeon module!

I understand UMS is deprecated, and I don't really need very powerful video performance on this laptop, but it would be nice to have nicer font rendering.
