I don't think this is caused by the input-layer. Linux is not passing
Fn-X keypresses to your BIOS. If you've enabled ACPI that ought to be
the reason for this.

Are you running XFree86 4.3.0?

Yes, but the bug manifests very shortly after starting the
kernel. I am 99% sure that it happens before init is even
started.
For a split second after the kernel starts, I am still able
to use
the Fn key. Then, all the sudden, I cannot. I am running
Debian
Sid, and I notice the modules loading about when this bug
manifests
itself. Even if I make my modules not load, the bug still
manifests
itself.

Thanks, Warren

Also, XFree86 4.3.0 seems to inhibit Fn key combinations on some
scenarios. On my laptop, I can't use Fn+F3 to switch between LCD and CRT
while running X.

Fn key gets killed before X. Also, it works fine in X when I am in 2.5.63.
