Why would you *not* have fbcon=y? Without fbcon, you will not have a text
console at all with Nouveau.

That is a little odd trigger for it, but still just an unrelated theoretical
issue of the case when someone wants to have graphics but not a console.

To the original poster:

You were asked to provide a complete kernel log from boot up to the original
failure. Do not filter it, do not interpret it, do not compress it. Without the
log you cannot be helped.

It is almost as if you do not have KMS enabled (or Nouveau installed properly).
The log will show the cause. When Nouveau loads, it will print many lines to
the kernel log at kernel module init time, before X starts.
