Does the mobile Intel 4 series express chipset (GMA 4500m) support 24 bit depth buffer?

Hi I want to buy Deathspank for the PC and it requires 24 bit depth buffer and Intel and Hothead games both told me it should work. Older versions of Intel cards had the option to change it but mine doesn't. I was wondering if anyone out there has this chip and plays this game? I want to be sure before I buy it. Thanks.
