just FYI:

i've (finally) linked my netbsd/sparc kernel with an almost-completely
dropped in /sys/vm from freebsd-current (well, from a couple of weeks
ago).  i haven't yet tested it (waiting 'til i get in front of the
machine first  :-).

i've also rewritten the vm_swap module to allow swap addition/deletion
on any device or file -- but i haven't yet ported it to the freebsd vm.

please, don't ask "can i help" yet.  once i get to the stage where i've
got a few things under control (ie, tested a bit  :-) i'll send another
email to here asking for testers.  :-)   but that could be anywhere
from later tonight to a month away  :-)

.mrg.

ps:  yes, i *do* enjoy the pain.
