It all depends on how the company that has the trademark approaches you.
The cease and desist treatment is common, but you have to determine whether or not it is a shallow or serious threat they are making. If they are a big company they may not even bother with any steps that lead to legal action, and instead they may appeal directly to ICANN. I think most large companies do this for copyright infringement they want dealt with immediately. They pay $1,000-$2,000 and in 10 days the domain is transferred to them, much cheaper and easier than a lawsuit.
The problem is you'd probably only register the domain to make money off of it in a misleading way. That is more likely to warrant real legal action.
If a company does not actively fight infringement on their copyright they can potentially lose it. So that's why you get all of the shallow threat cease and desist emails and stuff. They have to be able to prove they are "actively protecting" their copyright. They probably don't even really care if you keep owning ihategoogle.com or whatever, because that isn't misleading anyone, now if you own google.co, that's a different story.
Unless this is going to be making you a millionaire, I would just forget your idea. If you're dead set on it I would start by researching how the company you are trying to imitate deals with copyright infringement.
