This was the reason of my latest post : changing IRQ code not to scratch 
R2 is indeed mandatory but have you any evidence of "faster and 
smaller". I can understand smaller but not sure faster as you freeze one 
machine registers. Can you point out part of asm and benchmark to see if 
modifications are really worth?
