Anyone have a fast blowfish implementation for pentiums?

I have looked at two assembler implementations [1], [2] so far, and MS
VC++ 5 and GCC beat both of them!

Neither of the sources do anything about instruction scheduling to
keep both execution units busy on the pentium.

I should note that I am not using an Intel CPU, but an AMD k6 233
clone, which may or may not influence effectiveness of scheduling
tricks. Anyone know/done experiments on this?
