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
