Yes and no.

Not really. I wanted to know why the de driver wasn't recognizing my
NIC. According to the FAQ and the Handbook it is supposed to be the
driver for my card. Turns out it's not, but there ought to be a better
way to discover this than by sprinkling the kernel with printfs, or
try-each-one-until-one-succeeds, or
turn-everything-on-to-discover-which-it-is.

Seems to me -- from the cursory look-see that I took while figuring out
my card -- that the PCI ethernet stuff could be unified into something
like a single pci (pseudo?) ethernet device. That could be fun to hack
on.
