Hi Karl!

	That seems like a guest OS problem to me: Ubuntu likes to rename
devices, for example (see /etc/iftab).

Unfortunately, giving direct access to hardware breaks isolation: you
can tell that card to dma to/from anywhere in memory 8(

However, more efficient I/O is coming as part of the (multi hypervisor)
virtio work: the plan is that lguest will get all the virtio drivers for
free...

Thanks,
