DooV: thanks for your reply. Could you please point me in the right direction, I can't seem to find the problem that's causing the firewire issues.
I never had any issues with firewire before, I've been using the same hardware setup since 10.4.8, and I've updated the software whenever a new update came to the surface. I've been using the PCEFI9 (for about a year), but I decided to make a fresh 10.5.7 install and switch to Chameleon and give it a shot.
About the iopcifamily.kext - I never had to touch it to get the firewire working, it worked without any modifications.
Any information would be greatly appreciated, thanks.
edit: I'm starting to think, this is not a Chameleon related issue:
http://discussions.apple.com/thread.jspa?threadID=2014443&tstart=1edit2: putting it to sleep and then up again seems to bring the FW0 interface to the system. But the message in the system profiler changed to "Warning:
Unable to list FireWire devices." and it's still not recognizing my audio interface.

SOLVED! ... well, kind off -- I had to delete the AppleHPET.kext, cleared the kext cache, rebooted and it worked. But aren't I gonna need the AppleHPET.kext?
