Although when the stuff is not in the kernel, the syscall slots simply have
a NULL in the entry.  That is a waste of space, but the waste is on the
order of (a few dozen) * sizeof(void *)--rather negligible in context.

There's more than enough, yes; sometimes "without source" simply means "lost
source".  But that's why you get the ability to turn off the compat
subsystems if you don't need them.  8-)
