So, I went back to this, and di it properly. Booted single user mode, which worked, then installed world, mergemaster, and rebooted single user mode. ...and I get a kernel panic as I did before. So it wasn't the 11 world with the 12 kernel after all. Panic is reproduced below. I am somewhat stuck now though - where do I go from here ?
