windows vista upgrade advisor and Intel Integrated Graphics Media

Hi All,

I recently purchased Dell 640m with 2gb ram. it has pentium dual core and
Intel Integrated Graphics Media Accelerator 950 GM. Specs shows that Graphics
card can take maximum of 225mb of RAM. that is more than enough to support
AERO and GLASS interface for windows vista premium.

However when i ran windows upgrade advisor, it asked me upgrade graphics
card ( like it is easy to do on laptop huh!!!). When i checked the intel
site, the pdf says that
AERO experience supported on Intel integrated graphics chipsetsDesktop –
Intel®945G Express chipset and aboveMobile – Intel®945GM Express chipset,
No discrete graphics card required"
(http://cache-www.intel.com/cd/00/00/...387_335387.pdf, page 4).

I am getting little confused on whether AERO and GLASS will be supported if
i install WDDM drivers from Intel? in fact i tried to install WDDM drivers
downloaded from intel site and ran windows vista upgrade advisor again but
same result. it asks me to upgrade my graphics card.

Any suggestions?
