I did some more research and found this: http://touchd.sourceforge.net/
Looks like the touchpad might need some extra tricks... Either way, here's the

I got to compiling and running touchd (http://touchd.sourceforge.net/) and it
worked very well. There were a few problems starting it (segfaults) and the cap
locks LED doesn't work once it's running, but I think it's a good starting
point. From what I've read just adding the device IDs won't work for the MacBook
4,1 since the trackpad doesn't work like a synaptic device anymore.
Bug 445762 seem not duplicated Bug 445761, someone in ubuntu forum has solution

I tried getting that to work, 'usbhid' isn't compiled as a module so
unfortunately that specific fix won't work for Fedora but if we can get that

You can add this to the kernel boot options for the MacBook Air:
And this for the MacBook Pro 4,1:
keyboard patches are in kernel-22.214.171.124-34
oops, actually in 126.96.36.199-35
Perfect, I downloaded the kernel from koji and it works (almost) perfectly.
One thing I noticed is the F5/F6 keys for backlight control still report F5/F6
with fn or without it - Is this also part of the same bug?
Forgot to mention that F3+F4 (as in the expose and dashboard keys, not the
actual F3+F4 key presses) aren't detected by xev but no setkeycode messages
appears in dmesg either.
kernel-188.8.131.52-55.fc9 has been submitted as an update for Fedora 9
kernel-184.108.40.206-55.fc9 has been pushed to the Fedora 9 stable repository. If problems still persist, please make note of it in this bug report.
