The issue you are having is unrelated to Chameleon, the issue discussed in this thread was resolved almost two years ago.
Make sure you are running Chameleon 2.0 RC5.
We can not offer general Hackintosh support here.
There is a thread about your Firewire issue over on InsanelyMac, IIRC it can be fixed via DSDT. Use the forum search over there to find it.
