Frank,
I have found this text particularly useful when it comes to using MIT (or
BSD) code that resides in the GPL project (e.g. DRM in Linux)
http://www.softwarefreedom.org/resources/2007/gpl-non-gpl-collaboration.html
I think that sections 2.2 and 2.3 are the things to be careful about
because there is a non-trivial probabilty that at least some out of many
patches that come in from many authors were created by copying and pasting
lines of code that may have come from some other GPL'd code (e.g. other
parts of Linux). Nobody can guarantee that this has not happened.
P.S. The above is my personal opinion, I speak for myself, not for my
company, I am not a lawyer.

Xav, thanks for your reminder. Actually our law leam has already checked the
license. As Dave said, the DRM kernel driver is all MIT-licensed and we will be
free to use them. When the drm uses linux kernel function calls, we will use
freebsd(none-GPL) equivalent to replace.
Dave, by the way, I want to ask you about some exceptions in DRM. you know in some
files(i.e. drm_fb_helper.c), it includes MODULE_LICENSE("GPL and additional
rights"). Does it mean it is GPL licensed? Is it free to use this file?
Thanks,
Frank

I imagine you already have checked with your company's lawyers, but if I
understand correctly that means your drivers will be distributed under
the GPL ?
All the GPU driver code is licensed under MIT.
Oh, I thought "linux" meant "kernel", not "X11".
