I think this is probably what the lawyers are telling the graphics
card companies at the moment, the GPL is broken by the act of linking
and at what stage is the link considered to have happened, so if I
distribute a GPL or BSD licensed stub layer in source form, a big
binary blob that doesn't use any kernel interfaces except my stub
layer ones, and never distribute any of it with a kernel or linked
into anything, am I breaking the GPL on the kernel? all I'm doing is
releasing some source code and some binary image files, the user is
doing the linking by loading my code into their running kernel  and
I'm not distributing my code with the kernel...

It'll be an interesting day in court... and maybe then derived work
will become nicely defined at least for one country....

Dave.
