so here are two different configs 
<conf_1>
machine i386
cpu I486_CPU
cpu I586_CPU
cpu I686_CPU
....
....
</conf_1>

<conf_2>
machine i386
cpu I686_CPU
....
....
</conf_2>

for the first config i should enable it manually. (for a P4 machine)

and in second one it is enabled by default so i dont need to add enable
to kern. conf

should i put options CPU_DISABLE_SSE for P2 and P3 machines?

would not using disable option on a p2 machine with kern. conf like 
second couse any ill effects? like not being able to run the binaries compiled 
with -march=pentium4 ...

and is this enable disable automaticly has anything to do with CPUTYPE option
on the /etc/make.conf
