If you need to do file I/O to load firmware (as an example), either put the firmware in a discardable section (vm_deallocate() it after it's loaded in the card), or have a user space daemon communicate the firmware to your driver via a series of ioctl() calls to push the data *temporarily* into the kernel, so it doesn't take up real or virtual memory in your driver.

This comes up over, and over, and over again here. Is there any chance Apple can provide a centralized way to do this in the OS,

Yes. It's called a user-space process.

OK, what you mean is that it is called N user space process, a different one for each driver, all re-inventing the same wheel with different bugs.
