i like the second option.  i still use a pentium 166 as a router  and i have a 
cyrix based system here which needs i586 kernel  and until recently  also 
used a k6-2 system  needing i586 kernel also.  since there is not really any 
gain from i486 to i586 id go with the i486  i know of some people who use 
i486's for firwalls.   just my AU$0.02  soon to be US$0.02
