It is actually empty (or more exactly completely commented) :
% cat /etc/initramfs-tools/modules

In that case, it might just be an error from my part.
I am trying to get HDMI audio to work and while doing that, people helping me 
on IRC told me that these two lines mean that the problem comes from missing 
firmware.
I checked and the fact is that I have the firmware on my filesystem, however it 
seems that the radeon driver is loaded early so as to get KMS working 
correctly and therefore I looked at initramfs.
Comparing my initramfs with the one of someone with a similar setting (radeon 
driver / debian sid / update-initramfs generated initramfs) has shown one main 
difference: he has the radeon firmware in his initramfs and I don't.
so I assumed this might be the reason for the problem.

I'm sorry if I'm mistaken and wasting your time. Could you provide me some 
test that I could run to check for sure that the driver is loaded after the 
root FS has been mounted.

Thank you
