This means the radeon kernel module failed to initialize acceleration
for some reason. There might be more information in dmesg, but I suspect
the above firmware configuration is most likely wrong. Does it work
better if you don't enable CONFIG_FIRMWARE_IN_KERNEL and/or
CONFIG_PREVENT_FIRMWARE_BUILD? Then it should try loading any necessary
firmware files from the filesystem at runtime.
