Rick, I think that's it: lsinitrd lists the nouveau driver and points to 
the newly built binary in /lib/modules/.../updates/.

In older versions of the initramfs image in my /boot directory, the 
original driver is listed.

So, in your step 5, a simple "dracut" should do the trick (with the 
"--force"-option when the initramfs version corresponds to the running 
kernel). I found that dracut finds and includes the binary in 
/lib/modules/ .../updates/.

Thank you for pointing me into this direction!
