Actually it is the other way around.  The i686 kernel uses the cmov 
instruction which the the CPU doesn't have.  This means your CPU 
probably isn't at least a i686 (ex: old Via Samuel cores etc.)

Old distributions that have old i386 or possibly i586 kernels are 
probably your best bet if you need to support the hardware.
