That is now making more sense. DRM is getting loaded and preventing 
radeonfb from being loaded. Is the correct answer to turn off 
config_drm_radeon and make config_fb_radeon=y?
What is config_fb_radeon_i2c?
Should config_fb_radeon_backlight be y or m?

CONFIG_DRM_RADEON=m
CONFIG_FB_RADEON=m
CONFIG_FB_RADEON_I2C=y
# CONFIG_FB_RADEON_BACKLIGHT is not set
CONFIG_FB_RADEON_DEBUG=y

You want radeonfb, which is the kernel framebuffer driver and which has
the code to fix power usage during sleep.

IIRC I had to add radeonfb to my /etc/modules to get it to load on
startup.
