Can you dump the following registers using radeonreg or avivotool
(http://cgit.freedesktop.org/~airlied/radeontool/) with the patch applied and
reverted and attach both results?

CC_RB_BACKEND_DISABLE (0x98F4)
CC_SYS_RB_BACKEND_DISABLE (0x3F88)
GC_USER_RB_BACKEND_DISABLE (0x9B7C)
CC_GC_SHADER_PIPE_CONFIG (0x8950)
GB_BACKEND_MAP (0x98FC)

(as root):
radeonreg regmatch 0x98F4
etc.
