I thought that the following quote from the link I supplied might apply
since I thought your problem might be caused by the lack of a WDDM driver
but by a revised XPDM driver whose performace is degraded since it had to be
out of the kernal to run on Vista.
A: Intel will provide support for WDDM drivers beginning with the Intel« 945
Express chipset family and beyond. See question 5 below for a detailed
explanation of WDDM support on Intel« 915 Express chipset-based platforms.
However, Windows Vista is supported on the Intel« 845G, 865G, 915G Express
desktop chipsets and 852/855GM mobile chipsets running XPDM (XP Display
Driver Model) drivers for Intel graphics. Windows Vista will install on
these platforms, but advanced features such as Windows Aero will not be
enabled as XPDM drivers do not support Windows AERO.
