For what purpose?
Is it to build some sort of mob trap?
Yep...all for the fun of it
I'm on an Intel Q45/Q43 here
Dang...thing i have is for the 910's...but there was reports of 945's making it work with the same thing i believe...
Anyway, try the below, mine worked straight away...just make sure java is up to date etc

:
Note that this may not work for all but it works on my XP Dell Inspiron 1300 Laptop with a Mobile Intel 915GM/GMS, 910GML Express graphics card (crappy, I know).
*Download latest Minecraft client if not already present
*Rename the downloaded Minecraft.exe to Minecraft.jar
*Open a command prompt (go to start, all programs, accessories, command promt) and type the following command : java -Xmx800m -jar "C:\Documents and Settings\Brandon\Desktop\Minecraft.jar"
(RENAME THE PART IN QUOTES TO WHATEVER DIRECTORY YOUR MINECRAFT.JAR IS IN)
*Should open up Minecraft with no problems
Credit to darknesschaos.After you do that you can open Notepad and put the command that worked for you in that and save as MinecraftStarter.bat and you can double click that to play minecraft, it will start it up with those commands for you.
If this works for you please post your graphics card and system specs so we know better who this helps.
***UPDATE: THIS FIX SEEMS TO ONLY HELP INTEL MOBILE INTEGRATED CARDS USED IN LAPTOPS.
