from "Documentation/SubmittingPatches", at the very end:

   4) Don't over-design.

   Don't try to anticipate nebulous future cases which may or may not
   be useful:  "Make it as simple as you can, and no simpler"

it seems that, if that's good advice for patches, it should be good 
advice for the code proper.  i do appreciate your point, but if at 
some point, a shiny new register suddenly appears, that strikes me as 
a significant enough change that mods to the header file shouldn't be 
considered a big deal.

anyway, just my $0.02.
