I'm not actually sure of the gain from ffs, one of the main things it 
actually does though is get rid of all the looping and branching in the old 
way of testing each bit. I never actually got around to benchmarking it as I 
couldn't think of a decent benchmark (others did suggest printing on the 
riscpc as being a way to hammer the interrupts...)

I just never got around to redoing it on the hpcarm as hpcarm has now got 
generic soft interrupts as well (probably don't really complicate that area 
much but not had the time really) which we should really pull back into the 
arm32 derived ports.

Cheers,
