fistful: the reason ID gets equated to Creationism by so many people is that we don't hear ANYBODY but Christians pushing for it as a theory. If there were anybody of another religious group backing it, that would be different. Heck, from what you've described of it, sounds like ANY religion could endorse it. But it's only being pushed by (vocal) Christians...
I don't know if you're right about that, but if so, consider: Perhaps those of other religions are not concerned about whether their creation stories, or their sacred writings, are undermined by the dominant scientific theories.
Perhaps some have decided that evolution comports with their tradition. Some may have decided that their creation stories are not essential, and have abandoned them easily, keeping the rest of their religion intact. These options do not work for Christians, as evolution contradicts the basis of our worldview (Hugh Ross not-withstanding). Creation and the Fall of Man are central doctrines, which hold that death (at least for animals and humans) did not occur before Man sinned.
Perhaps some have decided to ignore scientific theory where it contradicts faith. This is where it gets interesting. Having read a bit of the Koran, and perhaps I need to read more, it seems to me that it is primarily a book of sayings about morality and proper conduct. These can be disagreed with, but not really proven or disproven. This differs strongly from the Bible, which concerns itself very much with history, with real events. It makes itself available to be proven or disproven by science or historical/archeological research. So far as I know, the Bible is given high marks for historical accuracy (at least as ancient manuscripts go) and doesn't directly contradict the truth discovered by science - unless evolution truly happened.* That's why it's a big deal to us. Maybe other religions don't much care, as they're not based in fact and history anyway. But that is just as I see it, not being a scholar of world religions.
*While many seem to think that miracles contradict science, this is just not reasonable. If God exists, there is no reason to think He would not suspend His own mechanical laws from time to time. Of course, moral laws are another story.
