graeme, I've read that too and we've tried it on a Huseberg 501e, although there were two of us.
We took off the back wheel, and put a big rock under the swingarm, then laid the bike over on the tyre to break the bead. It took one to steady the rear of the bike and one to do the pushing, but it worked. It also helps to spray a little WD 40 about the bead to aid it in breaking.
Another trick to reseating a tubeless bead if you don't have compressed air is to put a little parrafin around the rim and set fire to it. The short burst of explosion seals the bead and puts the fire out, yes it's dangerous, but it works if you're really stuck and not getting the bead to seat. Of course, you need to have parrafin with you, but petrol works too, if you're game.
