If you're thinking of something like the Nvidia driver, the binary
portion of that driver is cross-platform and is not a derivative work of
the kernel.

If you sit down and write a new driver for linux, is is arguable that it
is in fact a derivative work of the kernel and is thus subject to the GPL.

This may of course vary based on location, but I strongly suggest that
you consult suitable legal advice before proceeding.
