If Solaris has a "module-compatible" kernel ABI it's most likely possible
to be binary compatible considering we're source-compatible already
(cf. rump ABI compatibility with the kernel).  Of course it doesn't
happen accidentally and there's some amount of work involved.  But if
someone finds a use case for it, why not?
