	Perhaps it's not a separate work from the programs that access it, but it's
certainly a separate work from the kernel. The kernel can operate just fine
without the module. The module extends the kernel through a well-defined
boundary.

	The GPL says:

"These requirements apply to the modified work as a whole.  If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works.  But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it."

	So is a Linux distribution "a whole which is a work based on the" Linux
kernel? Would you argue that RedHat can't include proprietary software on
the same CD as the Linux kernel? All the software on the CD, assuming it's
Linux software, likewise extends the kernel through a well-defined boundary.

	DS
