: I wonder if they really must be recompiled. It sounds like that would

The cpl, cml, and interrupt lock variables and initialization of such
is gone, Kapoof. And the semantics have changed for a few things as well.
I haven't actually tested it to see if old modules still load and
operate properly because doing the testing properly would take more time
then I have to spend. If a KLD doesn't use spl*() calls at all it may
be ok. I think we should resign ourselves to recompiling the KLD's,
though.
