I have never been able to keep our ET Inc based routers any where near
up to date as far as kernels go, no, they don't use kld's, they use .o's,
but it is caused by the same set of problems.

I do know from interacting with Dennis at ET Inc that the changes
in the interfaces of the FreeBSD kernel have kept him from even trying to
be very up to date with driver code.

I also have a kld from a source I can't say, to support hardware I can't tell
about...  (No, this is not a straw man, it's called NDA red tape :-().
