Lubuntu 13.10 with a non-pae kernel

This isn't exactly related to non-PAE CPU, but related.

My equipment is mostly old and therefore became available to me at no 
cost.. :)
However, as much of it 8 years or older, some of the CPU capabilities 
required by newer kernels are not available to my cadre..

How would one go about finding out which CPU capabilities one has and 
which is the most up to date kernel to use for that CPU?

Last night I attempted to load Linux 12.04 LTS onto my 800 MHz Celeron 
and it was flagged and inappropriate due to lack of CMOV support.

Thus far, my incompatibility problems have centered around lack of PAE 
or CMOV capability.  Thanks for any insights on how to best match my old 
machine to the best Ubuntu Kernel.
