Hello Greg,
That's a good question, thanks. I was pretty sure that such information
is usually put at the top of the file. At least what I saw (to name a
few)

 arch/ia64/kernel/salinfo.c
 drivers/ata/ata_piix.c
 drivers/ata/ata_generic.c
 drivers/ata/libata-core.c
[..]

MODULE_LICENSE and MODULE_AUTHOR are at the top. Of course I can move
it back to original place, will resend soon.
