I have the late 2009 MBP, 2.8 GHz 512mb graphics card. It runs fine, though I can't set it to ultra, I have to keep it on medium. When I forget to switch graphics cards, the 9400m runs on Low settings, but it still looks pretty good on low, just more cartoony.I'd be interested to know this as well (have the same machine with the 512MB of VRAM option).
