What is left on the patch at this point are only bug fixes to panics and
overflows from the NetBSD port. This is not something I can test on amd64 and
rebuilding a kernel on qemu is painfully slow.
Unfortunately the svr4 emulation is incomplete wrt NetBSD; there is some rather
important code labelled "NOT_YET" that makes reference to UVM. I think the SVR4
emulation port still needs hacking from someone that knows well FreeBSD's inner
workings, but there is lot of work done already and it is no doubt a very
valuable effort in the light of OpenSolaris.
cheers,
Pedro
