It is not a component or modification of the Linux OS.
I looked at the kernel image included in the 538 update - it has been modified to include drivers for the e-ink controller. These are statically linked into the kernel, so definitely count as modifications for the purposes of the GPL.
Someone else previously posted saying that the boordr application also included GPL code (meaning Bookeen themselves would be violating), but I haven't checked that myself...
