I'll send this again because the first time I did I replied to some other 
thread and just changed the subject line, and I've since learned that this 
might not be the wisest thing to do if one wants others to see the mail...

Also the first version of the function was bloated as hëll because I hadn't 
yet realized how well [[ ]] handles variable comparison. Silly me.

So here it is again, this time much slimmer:

function is_kernel_minimum() {
  local CUR=`get_kernel_version`
  CUR=`expr $CUR : '\(^[^-]*\)'`
if [[ $CUR < $1 ]]; then
  return 1
fi
}
