Licensing my xnu code

[phcoder]

Hello, yesterday I received my copyright assignment and today I'll send 
it back signed. It obliges me to completely report about the state of my 
code. For creating xnu loader I used no other code then my own and 
different places in grub as a template. However I have previously seen 
APSL-licenced code. APSL doesn't extend to any reimplementation:
"1.3 "Covered Code" means the Original Code, Modifications, the 
combination of Original Code and any Modifications, and/or any 
respective portions thereof. "
"1.5 "Larger Work" means a work which combines Covered Code or portions 
thereof with code not governed by the terms of this License. "
As I copied no code I don't believe that this creates any problem 
however I fulfill my legal obligations by reporting it.
If this situation isn't ok for gnu project then I see following possible 
solutions:
1) I could release xnu loading as a third-party module
2) I could supply a description in plain English what the loader should 
do. Fairly complete i386 loader including Mach-O parser largely based on 
elfload is about 2000 lines of code
