The first place to start is /var/log/Xorg.0.log.
It should dump some pretty informative information that should explain why 
Xorg(1)
doesn't think it find a screen. :-)
Almost all my rigs use the Nvidia driver. I have found that only sometimes I 
must
also add the BusID:
BusID		"PCI:0:13:0"
Otherwise after loading nvidia, X seems to do it's job. Here's mine, in case 
it
provides any help:

# /usr/local/etc/X11/xorg.conf.d/driver-nvidia.conf
Section "Device"
	Identifier	"Card0"
	Driver		"nvidia"
#	BusID		"PCI:0:13:0"
EndSection
