I have a Dell M4800 and unlike IBM/Lenovo they didn't lock down the 
mini-PCIe slots to whitelisted cards. I replaced the Intel card with an 
old Atheros 801.11n card. If you're running FreeBSD 11 and the M4700 
contains an Intel card try the new iwm(4) driver. It isn't part of the 
GENERIC kernel and should support recent Intel wireless cards.

It depends. The Intel GPU is completly disabled in my M4800 because the 
Intel GPU can't drive the 3200x1800 30Bit display. Your Intel CPU 
contains a GPU, but there is more involved in a modern laptop with an 
additional dedicated GPU.

The simplest case is that the dedicated GPU is directly connected to the 
display and external video connectors. In this case you just need a 
driver for your GPU. Try the x11/nvidia-driver-340 first because the 
latest version lacks working VSYNC (you can thank the push to KMS-only 
and Linux GPL only APIs for this). If the GPU isn't supported by the 
older driver install the latest x11/nvidia-driver. Use nvidia-xconfig to 
generate a minimal xorg.conf.

If your hardware supports Nvidia Optimus things get more complicated. 
Nvidia Optimus is available with and without multiplexers. If there is a 
multiplexer there is a good chance that you can use the BIOS/UEFI oder 
ACPI calls to route the video outputs to the dedicated GPU or you can 
use the slower integrated GPU and save some power.

If you got the latest, cheapest and worst design there are no video 
multiplexers and the dedicated GPU has to pipe its video output through 
the integrated GPU. Maybe VirtualGL can help you in this case.

Put a supported modem card in the right mini-PCIe slot and send some 
magic AT commands to it (good luck finding the right datasheet). There 
are two ways to configure most cards. The simpler one is to unlock them 
and use them as USB ethernet NICs. In that case they will run their own 
DHCP server and you just have to start a DHCP client on the ue0 
interface. The more flexible setup is to use them as serial lines with 
net/mpd5.
