The NetBSD VM86() code is non-trivial to port to FreeBSD because of the extreme amount of differences in the i386 support in both trees. I spent some time after John Kohl's released his latest diffs attempting to port it to FreeBSD, but w/out a NetBSD system for reference it was impossible to determine the context for the diffs in relation to the FreeBSD tree. I know have a NetBSD tree for reference, but I have been swamped at work and my personal life has been crazy (trying to buy a house, stress from outside sources, etcc) so my attempt to get this working in FreeBSD has been laid aside to work on more pressing problems. If someone would like to pick up this work, I don't think it would take more than 20-40 hours to get it roughed-in to the FreeBSD kernel. At this point in time folks might be more willing to spend the time it takes to make it part of the standard distribution by cleaning up the bogosities that will undoubtedly be part of the initial port. If you're interested in *doing* the work, let me know and I can point you to the bits, or even provide them. Note, I don't have anything of substance as the hard-disk crashed on the portable my work was on. (How can I backup a stupid SCO box over the network since I can't get it to write data using 'tar cf - / | rcmd sun-box dd of=/dev/tape' which works on *every* other system I've used) Anyway, as of a month ago, someone who *was* working on the porting the code but they didn't expect to have much more time to spend on it, so there might be a starting point better than nothing as well.
