Firstly the double-quotes around numbers is no longer required (I
don't think it causes any problems if you still use them, but I'm not
sure).
As a failsafe way to make it work leave all these in your initial
kernel:
machine i386
cpu I386_CPU
cpu I486_CPU
cpu I586_CPU
cpu I686_CPU
Then look at the boot messages to determine which one is the correct
one for your machine:
# dmesg | grep ^CPU
CPU: AMD-K6tm w/ multimedia extensions (233.86-MHz 586-class CPU)
^^^^^^^^^^^^^
You can then comment out all the other ``cpu'' lines.
