I agree. That makes good sense.

There is another workaround for the issue. I've just discovered it here
If you use it you don't have to change original driver.

When you'd like to use ORe from L4Linux with Intel e1000 series NIC you can
circumvent the problem with stub driver wrong IRQ requested by giving
additional options to L4Linux command line (this cmd line is in .cfg file
that you load by grub). Like these one: "l4ore.oredev=DEV l4ore.irqnum=IRQ",
where DEV is attached device name discovered by ORe (e.g. lo, eth0, eth1 and
so on) and IRQ is irq number assigned by BIOS to this particular DEV (BIOS
usually prints irq assignment during boot).
E.g. in my case I could add to command line: "l4ore.oredev=eth0
Effectively these options force the stub driver to override device name and
irq returned by ORe server with specified one.

I didn't try it by myself but judging from ORe stub driver source code it
should work.
