Yes. That floppy driver could easily be a good case for using those 
threaded irq's. The problem, of course, is to find somebody motivated 
enough. The code-base really is pretty dang ugly, and it might be hard to 
do it incrementally, I think.

(And starting from scratch is likely not a great idea either - while 
_some_ of the ugliness comes from the odd irq-driven state machine code, a 
lot of it also comes from trying to handle all those floppy formats etc)
