I believe that you need to use the ATI Radeon beta drivers for the 3.11 kernel branch, I had to anyways.

Hey all,
I have just compiled the 3.11.5 kernel from kernel.org to fix the ACPI wont shutdown issue, but I have a couple errors in dmesg I am trying to figure out.
Can anyone point me in the right direction?
The errors are:
1:
dm_mod: module verification failed: signature and/or required key missing - tainting kernel
2:
[drm] VGACON disable radeon kernel modesetting.
[drm:radeon_init] *ERROR* No UMS support in radeon module!
