I'm sure your lawyers will do what they think is the right thing, and
you should listen to them more than to me ;)

the lawyers I talked to actually said this was not ok.
Either that part needs to be open, or it doesn't. BUT here is the catch:
if it does have to be open it HAS to be GPL. (there is no scenario where
it has to be open but doesn't have to be GPL)
and once it has to be GPL, clause 2 says the entire module has to be

"view" or "facts"... the license is what it is.

well from the bottom others are comming up. Intel and Via for example.
These have open drivers. Today Intel isn't there. The next generation is
apparently 3 steps further (according to the register), and you can see
the trend... nvidia and ati are scared of it. (so scared that they went
into chipsets exactly for this reason)

That is a mischaracterisation; just because you don't agree with someone
doesn't mean he is a fundamentalist.
Linux got where it is today BECAUSE it requires drivers to be open.
That's just about the ONLY difference that made it that linux and not
BSD because this leading open source OS.

well to some degree.. if you need closed drivers you're giving away the
biggest gain you got with open source (flexibility and freedom), so why
use open source then? (you can say the same about using enterprise

yeah, in that world those people just go over the disassembly instead ;)

today? No. Why? because too many people accepted a binary driver as
normal, so much so that ati stopped supporting open 3D.
sad but true. Note that being in the kernel is fully NVIdia's choice.
All other 3D drivers have the part that nvidia considers IP in
userspace. (well ATI is now copying nvidia on this one)
NVidia doesn't want that mostly because they do it in the kernel in
windows, and they think they will loose 0.5 to 1% performance (due to
paging overhead). But it's their CHOICE.
