One way around this (if we can't probe for SWIM vs. IWM), is install "I 
Wish I Were" and set the Gestalt ID to 7 (Mac IIx). It works on my Daystar 
'030 Mac II; it may work for you too.

I've seen this with more recent kernels. Not sure about 2.6.18. It happens 
because a proc file is registered twice by the nubus probe code. It is 
only a cosmetic problem, but I have been working on a patch for it.

My machine does that sometimes too. I blame the aging 
powersupply/capacitors (either too slow to reach a stable voltage or too 
quick to come out of reset) but I'm guessing.
