Yeah.  But if the kernel is GENERIC its got wildcarded devices, and if
its not GENERIC, then in an ideal world you'd edit a config file,
rerun config, and rebuild....

There are other good reasons to want this functionality, tho.

You mean at the end?  I dont think that helps: order is signficant,
and patching in "spare" entries would  mean re-ordering the array.

I think that goes beyond the normal meaning of "patchable".  

To do it Right you'd have subsumed the FreeBSD boot-time
config state, even.
