Are there any semantical differences between the two? A: yes, you can only unlock a mutex from the thread that locked it. So I guess my only options are nameless pipes and named semaphores.

The overlap between the driver models is pretty much that both systems use compiled languages for kernel modules. I agree. The IOKit does things very different -- IMHO better -- than Linux. A lot of people here on the list surely have had the task to implement a Linux driver to OS X. If you have specific questions, you should post them.
