Try "I486_CPU" just because AMD, Cyrix, etc says the processor is a
586/686 doesnt mean that all intel 586/686 features are supported.  I
needed "I486_CPU" for my Cyrix 6X86. Don't let the clone companies
marketing literature fool you with regard to something as complex as a
cpu being an exact duplicate.  Intel's stepping levels are different
models of the same CPU. You should also read LINT and look at the
options for the different CPUs. Look at dmesg and see what the install
kernel says it found and use that CPU.
