It's got nothing to do with the hardware. request_firmware() reports sizes of
the files in question which do not match the sizes of the files on your system
(which match the expected sizes). So something goes wrong between your
filesystem and request_firmware(). The most likely explanation seeming a
problem when copying the files into the initrd, or maybe
/lib/udev/firmware.agent in the initrd doing something wrong or something like

What does

 gunzip -c /boot/initrd.img-$(uname -r) | cpio -tv | grep CEDAR

> Boot with "radeon.modeset=0 3"

The '3' won't have any visible effect on a Debian system, you'd need 'single'
for single user mode.

It does include something (otherwise the failure would be different), but
possibly not the correct files.
