I spent much of the extended weekend (Friday was Doljatra & Good Friday) trying to get the camera on my Intel Macbook to work on Fedora. You can find almost all the non-Fedora specific information is available at http://bersace03.free.fr/ift/.
So I went ahead and created a RPM (review request: #438561), spent some time fiddling with udev because I was not getting a /dev/video0 to represent the camera, and then discovered that the USB device ID (obtained from lsusb) had to be explicitly specified to ift-load to get the firmware to actually load on to the device.
As mentioned on http://bersace03.free.fr/ift/ Ekiga was a breeze to set up, but Cheese was not. Cheese 0.2.4 which ships with Fedora 8 kept crashing with a SIGSEGV somewhere deep inside the GStreamer library. It was a classical case of strcpy(des, NULL). So one has to grab Cheese 2.22.x from Rawhide and update GStreamer accordingly. If you happen to have the gstreamer-plugins-bad packages from Livna then you might be in for a 350MB download. You have been warned. :-)
