I tried this out on FreeBSD 4.8 with a Procom 155B and it works great
with the minor patch below (since aux doesnt exist in the 4.8 mbuf anymore)

One question: I'm trying to access the device in AAL0 mode, to gain access
to the raw 48-byte payload.  Does the procom driver support this?  Comments
in the driver suggest not.  I've tried a quick natm program, and that also
failed. 

Could someone suggest a good way to do AAL0 on a Procom card?
