I found a solution on this blog linked below. Even though I don't have a Dell
700m, I have the same graphics adapter, and this suggestion to manually
install the driver works:

Quote from this blog:
"Even though this post is not directly related to Dell 700m Intel Display
Cards and Vista drivers for these cards a lot of people seem to be googling
their way to this page in search of similar answers. This update might help.
If you are running Intel(R) 82852/82855 Graphic Adaptor on Your Dell 700m and
are having problems switching to clone mode with Dual Monitors or running on
a Projector by pressing Fn-F8 key, start your Add New Hardware Wizard on
Vista, select the manual driver installation process, choose Display Adaptor
in the type of device and from the list of drivers Vita offers, choose Intel
as Manufacturer, and "Intel(R) 82852 / 82855 GM/GME Graphics Controller
(Microsoft Corporation - XDDM)" as your driver, even if Vista had detected
your driver successfully during installation. Complete the Wizard and Reboot.
Once the reboot is complete, you should be able to see two display adaptors
with the same name installed in your Device Manager. Now disable Extended
Desktop and should be able to switch to a projector or clone your desktop on
your second monitor using the Fn-F8 key."
