Beta5 was a strange beast, and it is the only one with IOP 11. You need to run beta5 tools with a beta5 kernel. Otherwise, you should run beta6 tools with beta6 kernel, or beta[234] tools with beta[2346] kernel. I don't recall which problems were fixed beta5 -> beta6. Is it possible for you to get another kernel (beta6 preferrably) so you can run beta6 tools?
