Failure vs. non-failure of allocation of a kernel managed physical
resource can't be determined by a userland process which may or may
not be running.

In fact, if I build all of my drivers built-in and use NFS root which
will activate and bring up network devices, userland won't even be
present when the interrupts are requested.

No, you really can't do it this way, IRQ allocation management has to
be in the kernel.
