I just went through this. You have to use the tristate conduit control. There are some PDFs describing how to do this, but you will have to search. I can't find the links now.

I spent a week getting QSYS to compile with an existing SOPC design and in the end I ran into flash programming problems and on another brand new design it wouldn't even run in the debugger. There were may errors and workarounds that you have to discover. I would suggest staying away from Qsys and stay with SOPC until a few more release. Hopefully they will get more bugs ironed out in a year or so. It just wasn't worth the trouble for me to continue beating on it.
