And Linux kernel is under GPL v2, so it must be OK. It'd be better to
add the note that this firmware data is copied from the linux kernel
tree and show the kernel license (GPLv2) explicitly for emi2|6 stuff,
together with the original copyright of the driver source code.
I think other firmwares copied from the kernel tree (maestro3, ymfpci,
etc) should include the similar note, too.
Clemens, could you add that?
