I unearthed an old CD which happened to have my old hashcash-1.08  
binaries on it.  This achieves over 10 Mh/sec per CPU on my 2.3GHz G5  
- without any fancy GCC4 tricks, and possibly even lacking some of my  
later optimisations.  Thus, as I've just set off a pair of 40-bit  
minters on it, I expect to have a result in about 14 hours' time.
