Yes... it is fine. It comes standard with tthat Rom and kernel.
Also... just some advice. In order to keep the forums as "clean" as possible, you do not need to start a brand new thread for every question.
Instead, for example, this question (as well as your last two posts) were referring to the CM7 rom. The official CM7 thread is a more appropriate place to post duch questions. One, for keeping the board clean as I mentioned, and two... you will get a lot more people to see ypur question and offer help/advice. All three threads you started could have been asked in the original thread.
