Why do it by hand when you can modprobe? I don't use nouveau myself, but
om my machine (running v3.18.1) modprobe tells me:
$ modprobe --show-depends nouveau
insmod [...]/drivers/gpu/drm/drm.ko
insmod [...]/drivers/gpu/drm/drm_kms_helper.ko
insmod [...]/drivers/gpu/drm/ttm/ttm.ko
insmod [...]/drivers/i2c/algos/i2c-algo-bit.ko

insmod [...]/drivers/platform/x86/wmi.ko
insmod [...]/drivers/platform/x86/mxm-wmi.ko
insmod [...]/drivers/gpu/drm/nouveau/nouveau.ko
