Ok, can you get a stack trace?  The only time I've seen these recently was 
when the 8259A wasn't truly shut down correctly during boot and it fired an 
interrupt before it was shut up.  Hmm, I thought Peter had added some hack 
code to just shut the 8259As up during boot, but now I can't find it.  Ah, 
it's earlier in that function.  It might be that his hack is incomplete as it 
assumes the 8259As are in a certain state, and if they aren't then his hack 
won't work.  I'll try to flesh it out some more.
