--- Comment #4 from Emil Velikov <emil.l.velikov at gmail.com> ---
This case reminds me XKCD's "Workflow" [1]

Please note that KMS is not only about "shiny boot splash". Here is a snippet
from Arch's Wiki [2]

"...
Kernel Mode Setting (KMS) is a method for setting display resolution and depth
in the kernel space rather than user space.
...
even kernel space power-saving.
..."

Not to mention that there were(are) a few cases where the handover
(vga->nouveau) was causing issues. With that said I believe that udev(or
similar in your case/distro) should kick in and load nouveau before X

Personally I do not feel to strong either way, thus it may boil down to
convincing the maintainer that "nouveau kernel module should not be loaded
before X" :) . In which case this patch will be committed
