Can you get the : output from /usr/src/tools/tools/pirtool for your machine? Once upon a time, I encountered many BIOSes that would happily map the first interrupt on an interrupt pin at the PIC. Further ones would result in an error, so I made the code ignore errors all the time. Looks like they are no longer ignored. I never found out if ignoring the error was OK or not, since the documentation was a bit thin in that area.
