Vostro 3700 and Geforce 330M drivers (post-300 version)

Edit:
After trying again with the latest drivers and starting from scratch I've managed to get the installer to detect the card correctly, but after the install both my Intel and nvidia cards are showing up with exclamation marks in device manager.

(My previous attempts were accidentally using the wrong Section numbers it turned out)

Does anyone have any information as to how to specifically install the drivers in the same way the 29x drivers worked? Is there any workaround?

I was considering flashing the graphics BIOS to have a more "official" hardware ID, but due to it's hybrid nature I'm not really willing to risk it.

I have tried normal nvidia drivers, Verde drivers and Beta drivers.

I've got a Dell Vostro 3700 with the hybrid Intel/Geforce 330M chip, Dell haven't updated their drivers for years and (presumably) becuase of the hybrid nature they have used a non-standard hardware ID on the chip itself.

This means I cannot use nvidia's updated drivers, the pre-installation check shows no compatible hardware error. I'm familiar with the hacked inf methods (here), adding my device's hardware IDs into the right places of the driver that it gets installed. This method seems to have stopped working since about version 296 (or so).

Here is my Hardware ID set:

PCI\VEN_10DE&DEV_0A29&SUBSYS_044F1028&REV_A2
PCI\VEN_10DE&DEV_0A29&SUBSYS_044F1028
PCI\VEN_10DE&DEV_0A29&CC_030000
PCI\VEN_10DE&DEV_0A29&CC_0300

This is to be run on Win7 64-bit.

I've also tried using the most recent LaptopVideo2Go drivers (which include other 330M models) and adding my hardware IDs to the INF. These install but do not work. Both the Intel and nvidia chips show with exclamation marks in device manager, saying there was a problem with the driver.

I cannot disable the Intel card via the BIOS (the ability was removed from the production 3700 models for some reason, presumably to make my life harder)

Any help is really appreciated.
