Well with the time it takes to compile the kernel (and worse the Kconfig
changing quite a lot between the endpoints) it's not fun at all.
Thus I will first try with reverting below few commits.

I will try out when I am back next to that machine.
If it's fbcon acceleration (which I assume as output to fbcon causes
new errors), probably one of the few commits to
drivers/gpu/drm/nouveau/nv04_fbcon.c would be the cause:
1167c6bc51880cb74a3b1a02286fc25392684281
drm/nouveau: allocate device object for every client
9dec9280523157da820f923e18dd6a7bf99fead7
drm/nouveau/fbcon: make use of drm_fb_helper.dev
28668f43b8e421634e1623f72a879812288dd06b
drm/nouveau/fbcon: fix font width not divisible by 8
f045f459d925138fe7d6193a8c86406bda7e49da
drm/nouveau/fbcon: fix out-of-bounds memory accesses
4dc28134a8c124aa01b441e1e5b8b54312edc5dd
drm/nouveau: rename nouveau_drm.h to nouveau_drv.h
At first glance I would suspect one of:
28668f43b8e421634e1623f72a879812288dd06b
f045f459d925138fe7d6193a8c86406bda7e49da
