Typically -- assuming things like the MMX instructions haven't entered the
picture -- it will work but won't show any great performance advantage. 
The DES library we use in FreeS/WAN (an early branch off what later became
the OpenSSL library, I think) has an assembler assist which nearly triples
performance on the earlier Pentiums, if I recall correctly, but shows very
little improvement over the C code on AMD K6s (haven't yet run timings on
more modern machines).
