The kernel is smaller with the enums:
          text     data       bss           dec             hex  
11438123   730686   2998048   15166857   0xe76d89  
11437787   730686   2998048   15166521   0xe76c39

The first is with the #defines, the second is enums.  The enums caused 336 bytes 
less code to be generated, so presumably the enums enabled some "optimization" 
that wasn't expected.
