Why not make them all tweakable in the loader.rc, rather than having to patch the kernel.
Actually, thinking about this a little more ... The loader knows where all symbols are in memory. Why not a general mechanism to let you reassign the value of any "variable" used in the kernel or in a module. I presume that the loader allocates bss for the kernel and each module as it loads it. So I presume I can assign a value to a variable that would ordinarily take on a 0 value, too.
