Hello David,

this cannot be related to nvidia drivers because of two things: 1) the
drivers are loaded after the kernel boots and 2) the proprietary nvidia
drivers do not support KMS (and according to nvidia they are not going
too in near future).

Make sure, you have nouveau blacklisted
(/etc/modprobe.d/nouveau_blacklist.conf) because you don't need it when
you use the proprietary drivers and last time I tested it, it had
problems with the vga boot option.
