Ask a lawyer not a kernel hacker. The license is quite clear that if its
a derivative work it must be GPL. Whether it is derivative is a matter
for lawyers to ascertain and you should consult a good one if you wish to
go dancing in minefields. In particular it is wise to remember that the
copyright holders including almost every other large cpu vendor and so
will include their competitors....

As to the spirit, the answer I think is: no.
