Yes I'm pretty sure:
(a) the kernel does a sanity check on SLITs and replaces them with a fallback if they're bogus. Even that is not strictly needed for correctness, just for performance. (b) SLIT information is only an optimization, but does not really break anything if it's wrong. In the worst case your scheduler domains or your zone fallback lists are not quite optimally set up, but they will still work.
