I'm assuming you have a PCI Express graphics card. Do you have PCIE support activated in your kernel?

I am not sure if my card is a PCI Express graphics card. I check my menuconfig and as below:
[*] PCI support
PCI access mode(Any)
[*] PCI Express support

I am not sure if the "no devices detected" means there is no /dev/nvidiactl and /dev/nvidia0.
I saw those two files before(may be when I set nouveau in VIDEO_CARDS......)

Now I even have no idea of what goes wrong, the kernel configure or the nvidia drivers

Sorry, I'm really at a loss here. I've installed/ updated Gentoo on machines with nvidia quite often, but I never ran into problems such as you describe.

What I do is:
Activate PCI Express support in kernel
Deactivate any NVidia Framebuffer related stuff in the kernel
put VIDEO_CARDS="nvidia" (and whatever else I happen to have) into make.conf
emerge xorg-server, nvidia-drivers, etc.
run nvidia-xconfig
startx

As far as I can see you did all this. :(

The only clue now may be the disappearance of nvidiactl and nvidia0 under /dev.
Or I will reinstall the whole system at this weekend.
Thank you as same :D

"If you use the proprietary driver from nVidia and the X server fails to start on a udev-only system, then make sure you have the nvidia module listed in /etc/conf.d/modules."
from http://www.gentoo.org/doc/en/udev-guide.xml
but I tested and also doesn't work ....

Sorry missed the hybrid graphics.
As far as I know linux does not have the ability to run hybrid graphics with nvidia video cards, there is a bumblebee project but not successful so far.
I believe there is some reported success with using the nvidia card in cases where the nvidia card can be enabled and the intel card disabled in BIOS.

Do you have a choice(s) in BIOS that enables or disables the intel video card and/or enables or disables the nvidia video card? Do you have a choice that disables switching?

I would get intel working and then fool with nvidia later.

VIDEO_CARDS="intel" in make.conf

In case you have not found a solution yet:

Perhaps X (or nv/nouveau, respectively) can't read your monitor specs.
No monitor, no screen ....
If so, then, with your kernel configuration,
- enable all relevant I2C options
and at the same time
- disable nvidiafb since it blocks other graphics drivers.
Resort to vesafb and optionally enable alternative framebuffer fonts.
Then recompile your kernel.

Btw: Have a look at /var/log/Xorg.0.log. It's quite informative.
Also look for i2c at wikipedia.
