Yep. I have not complained about those which are not obviously microcode.

Putting burden of proof in the wrong place, again. At the very least, if it
looks and smells like machine code, and I have no evidence that it isn't,
I'm going to assume it is. Anything else would be stupid.

How about the label "microcode (from ATI)"?
Anyway, perhaps you're thinking too abstractly.
For any given blob, the question is "is this the preferred form for
modification?" If it looks like it's a large quantity of microcode, then
given that almost nobody hacks large quantities of microcode in hex, we
figure it's probably *not*. If it looks like it's something else, we deal
with that in the way that's appropriate for that.

No, that's not right at all. It's a *particular* blob we're talking about,
and it's the factual question of whether it is the preferred form for
In the cases which have been removed, I haven't met anyone who's admitted to
modifying the 'blob' form of microcode, and it's a form which is almost
always modified in a different form. (If people said "Oh yeah, we modify
the hex," that would be factual evidence that it *was* the preferred form.)
In contrast, in the case of the various lookup and transformation tables in
the sound drivers, which are *also* hex blobs, their creation is
documented, and I can believe (in some cases) that they are modified by

The firmware hunks we're talking about are definitely executable programs,
though. Nobody has actually claimed that they aren't. Although some
people have claimed that "we don't know", we're actually pretty sure. So
Debian requires source for them to go into 'main'.

Do you mean "to be software, but not to be programs"?

Well, your statement as given confused the heck out of me, but if my
'corrections' are correct, then indeed the latter one (software is a
superset of programs) makes more sense.
There are none so blind as those who will not see.
