Uh? If the nouveau kernel module is loaded, the nvidia kernel module

Me. As per google, add "nouveau.modeset=0 vga=0x318" to the end of the
kernel boot line.
$ lsmod | grep '^\(nouveau\|nvidia\)'
nvidia 8096992 34
nouveau 568932 0
you're a bit late to the party. =) we've since confirmed that the two
can co-exist in some cases but not others. we're not sure the exact
intersection of module configuration / hardware setup that determines
when it works and when it doesn't, though.
Though the nouveau module is loaded, nothing's using it (as evidenced
by the 0 in final column). nouveau.modeset=0 keeps the kernel DRM
from touching the hardware via nouveau, likewise the removing rhgb
from the boot line. vga= explicitly uses the bios(?) vga support, again
sidestepping nouveau. When Xorg starts, configured with nvidia, it's
the first driver to access the device (not counting the VGA abstraction).
nouveau may have scanned the bus and knows that it could run, but nothing
has opened the device via nouveau. Coexistence is possible.
