By the time you've finished reading the copyrights from all the kernel 
files, you'll know that I'm referring to this license:

 * ----------------------------------------------------------------------------
 * "THE BEER-WARE LICENSE" (Revision 42):

That's 'options GPL_MATH_EMULATE'.  It's only useful on 386 and 486sx 
parts.

You'll have to go a little further than that; there are a large number
of individuals as well as Intel and CMU (at least) that you will need to
credit.  I'd recommend working out which kernel components you're using/
likely to use, then feed each of the files through head -50 and sort
them.  You'll only need to do it once; it's been a few years since I 
did the sweep for a previous employer, and it was pretty painless.
