DUL I guess.  Just use your ISP's smarthost instead of attempting to
deliver directly should fix that.  Or try kraxel@debian.org instead.

Right now I just have entries in a struct pci_device_id[] array ...

Yes.

It shows up in /sys/bus with that name.  I don't expect name clashes,

That is the PCI config space (PCI latency is in there too, if you load
bttv with "latency=..." that change likely is visible for the .1
function too).

so you don't have to (mis-)use the Nebula entry.
