Hmm, an educated guess here would be: if it's a userland versioning problem,
pppoe is the unlikely candidate. PPPoE ioctl have been changed to a completely
new, versionable ABI. The old ones, before that change, would not work at all
and certainly not cause a panic. The new ones can be freely interchanged and
still will work for all (the very few) revisions they made in-tree and still
not cause a panic like Rick described.

On the other hand, the ipf/ipnat ioctl are know to not be (a) versioned nor
(b) backward compatible. Downgrading them (for experiments sake) means:
get old source, install old headers (make includes in sys at least) and
rebuild ipf and ipnat.

But there seems to be no change in that part of the source tree at all
ever since November 16, 2001.

Anyway - good to know it works now
