I think this is it ->
http://www.usenix.org/publications/library/proceedings/bsdcon03/tech/eiraku/eiraku_html/

They used NetBSD, and modified it's ptrace() in a pretty minor fashion.
They also hacked out the BIOS calls from a FreeBSD 4.7 to make it easier to 
run (they don't have a VM8086 emulator :)

This is some pretty neat stuff!
