OK. Thank you for the explanation.

I know. The only platform I'm personally affected is 64-bit PPC using
petitboot. But I can compile SCTP in the kernel and have no problem
with this limitation.

However, loading with kld_list and Marks patch to run sysctl initialisation
after that would be a perfect fit for an SCTP module. I really like that,
but I have no idea whether this fits in the architecture or not...
