From your prior posts, this is not too surprising; others' reports here seem to indicate that things are usually approved rather quickly, or not at all. Your situation doesn't sound encouraging, from what you have posted .....
You might start by double-checking with your client as to whether or not there were any discrepancies in the information they provided to DreamHost at sign-up. Others have reported that things like false addresses, phone numbers, etc. have caused problems in the past; DreamHost does not host "anonymous" clients, and requires "real" information to create an account in addition to "payment".
At any rate, there is nothing that any of us here in the forums can do to help you; you should discuss the matter directly with DreamHost.
Actually, the wiki article I assume you are referring to says:
Note that it says
"may be approved within 24 non holiday hours", not will be approved.
As we don't know what the circumstances are that resulted in DreamHost declining to host your client, I don't know how the article could/should be modified.
