I have it on a laptop, I'm still wondering about it...my card officially doesnt support hardware TnL according to the intel site, but it plays a lot of games that list it as a minimum spec...meanwhile, it also plays Civ 4 apart from the black terrain and cheshire cat bug.
I think that the black terrain problem is seperate from any TnL issues as the terrain can be made to appear by altering the mapvisible value for starting techs.
Meanwhile, the cheshire cat bug does seem to be TnL related.
(It's an intel 825/855 graphics card btw)
