- When you say "FastCGI isn't working", did you try the sample scripts from wiki page on FastCGI to make sure that it's the setup rather than an issue with your script's interaction with the way FastCGI is setup at Dreamhost?
- Did you enable FastCGI for the site that you're experiencing the problem and did you report that site in your trouble ticket?
Apologies for the annoying confirming questions, but it's my nature to try to help with people's original issues rather than just simply providing the minimal possible answer.
Anyway, to answer your original question: Dreamhost has this slightly annoying policy of not replying to support tickets until the problem is resolved. That is, if you're asking them a complex question that takes a while for them to figure out, you may not get a response until they fully figure out what's wrong.
FWIW, I always recommend creating a "test case" that is the simplest possible thing that could possibly work and submitting that to support as a tool to aid them in debugging your issue (or at least proving that it's a configuration issue rather than my own poor coding skills or misunderstanding of how a feature is supposed to work).
