linus cant alter the GPL, which is gooooood :-), he cant change the license at all... Imagine the people that would sue :-).

It has long been held that linking to GPL code is suffient to
consitute 'derived work' status, hence the existence of the LGPL.
The NVidia shim makes use of several kernel subsystems, the PCI
device layer, the VM, the module system (well really, the kernel
makes of use of the functions the module provides :) ), IRQ
subsystem, the VFS, etc.. These systems are rather large bodies of
code - without which the NVidia kernel driver could not work.
So I am not quite sure on what basis one could argue the NVidia
driver is not a derivative work, and hence it seems to me the NVidia
driver is technically in material breach of GPL.
You seem to be basing your opinion on:
"the nvidia driver uses only the standard interfaces to hook into
the Linux kernel"
How are the standard interfaces not covered by the GPL?
I know Linus' has often posted to l-k that he doesnt care about
binary only modules as long as they stick to the exported interfaces.
However, are all the kernel developers agreed on this? And if so, can
this exception be formalised and put into the COPYING file? If not,
then is NVidia not in breach of the kernel's licence?
