[ Obligatory IANAL sticker. ]
Clear case for me IMHO. If your code is GPL (and which you emphasize
with MODULE_LICENSE(GPL)) and then link in a binary blob, then the
combined work becomes GPL, and you are required to hand out sources for
it, including for the blob.
I won't mention the gray possibilities because it is just evil in the
first place to begin with.
I think (but I may be wrong) that e.g. "GPL+BSD" fall into this. (Which
not change the fact that you are still obliged to comply with the GPL.)
