What if (as I suspect David meant) I just want to exclude *some*

Linux gives you yes/no/module control at kernel config time for each
feature.  That's a start but I suspect what many want is "no feature
_X_ under any circumstances".

I think the simplest way to get that is to load a list of acceptable
modules and their hashes into the kernel at securelevel 0 during
boot and make it unchangeable when securelevel > 0.  We very nearly
have the infrastructure to do this already.
