Can you send your complete configuration file and startup command file? 
I'm guessing you haven't enabled things properly in the startup command
file or in the configuration file, and if you don't do that you won't
get a valid BMC.  It looks like it's connecting, just not working right.

Also, what version of OpenIPMI did you try?  The latest git release is
probably the best.

I just tried it out, BTW, and it worked ok for me.
