If your code is licensed GPL or greater rights then you shouldn't have a
problem. The module loader recognizes

"GPL"
"GPL v2"
"GPL and additional rights"
"Dual BSD/GPL"
"Dual MIT/GPL"
"DUal MPL/GPL"

as legitimate users of _GPL. Any work which is derivative of the kernel
(which in practise I suspect means almost any module) will need a GPL
compatible licence anyway.
