Add chipset id
From notebook driver 179.48 inf files
This chipset is listed as 8200M G in the driver inf files:
DEV_086F&SUBSYS_11511734 "NVIDIA GeForce 8200M G"
DEV_0845&SUBSYS_67201462 "NVIDIA GeForce 8200M G"

However there is evidence on the net that it comes out as 9200M G:
02:00.0 VGA compatible controller: nVidia Corporation GeForce 9200M G (rev b1)
The 9200M G and the 8200M G don't have same GPU

I think the "9" is a typo!
A "GeForce 9200M G" doesn't seem to exist. There is a "9200M GS" with another ID, and the "9200" without any letters is not a notebook chip. On Nvidia's driver compatibility lists you'll find TWO "GeForce 8200M G" with different PCI IDs.

My conclusions:
There are two slightly different notebook chipsets named "NVIDIA GeForce 8200M G":
"MCP77MV" with ID "0845" for AMD CPU chipsets,
"MCP79MVL" with ID "086F" for Intel CPU chipsets.
This one is the "Intel" model, the second of the two, while an "NVIDIA GeForce 9200M G" (note the "9" in the name) does probably not exist at all.
I'm not sure about the codenames ("C77" vs. "MCP77MV", and "C79" vs. "MCP79MVL"), perhaps "GPU only" vs. "whole chipset"? Hence I put the whole string into the note and left C79 there.
There ar most likely quite a few different subsystems depending on the laptop model and manufacturer.

Reading the discussion here, it became clear that memsize thought this was a 9200M G because lspci said so, and that lspci said so because the name was already in this database (added by pchen).
I will change it to 8200M G for the time being, while I am having this researched. At this moment I think you are right.

C codenames are used for northbridges in dual-chip chipsets (which NVIDIA used for Intel platforms at first, because Intel did not yet integrate the memory controller into the CPU). But this chipset is a single-chip one so it'll be MCP79.
NVIDIA has been pretty confusing about their codenames however so maybe even both C79 and MCP79 are about "right".
