Need video driver package for Solaris 11

I'm trying to install Solaris on my laptop for training purposes. It recognizes all the hardware except for the Intel Mobile 4 Series (GMA 4500m) video controller. Wikipedia says that Solaris 11 does support Mobile 4 Series controllers but for some reason it doesn't have the driver for it out of the box. I need to find the appropriate driver package and download it. Google hasn't been much help.

Apparently the display still works without it (Generic Driver?), but just in case I have to do some light video processing I'd like to have it.
