I did it here (with Stephen's patch), and I still get the bug in vi. The various YP bits (in particular portmap) seem pretty stable. [ The only problem I see in YP (And it is almost certainly not related to VM) is that I get "rpc.ypxfr timeout"'s whenever I try to push the maps from the 386 onto my Old-Faithful 486dx. (The timeouts happen on the 486).
