I have similar mileage.
I started with iDeneb 10.5.6, then Software Update to pick up with Airport fixes.
Without running the brcm scripts on the forum, my 4328 was working!
I then downloaded the iDeneb 10.5.8 combo update, but somehow the the Voodoo 9.5.0 kernel failed to boot afterwards.
So I popped in the iDeneb 10.5.8 Lite DVD and upgraded the kernel to 9.8.0 Qoopz.
- Video 1024x768 only
- Skype crashes as soon as the connection is made.
The webcam worked right after I installed 10.5.6. iDeneb took a pic of me during initial config.
But image Capture failed to detect it anymore. :-(
