Wow, you certainly have a far bigger media library than me, unless you
are using a ridiculous amount of tiny disks. :)

Don't phone - email. Or, better, write an actual letter. The drones on
phone support are so often useless, but they do have the ability to
forward questions to people who can actually answer them. It is more
likely that they will do this with a mail request than a phone call.

If they are simply re-branding something that is actually made by
another manufacturer, then contact _them_ directly. Go to the top, and
make lots of noise. It's the only way to be heard by some of these
people. Be sure to let them know that you *want* to be a paying
customer, if they can only clarify what they are actually selling.

I agree. And be sure to _tell_ them that. Make noise when they don't
support Debian. If nobody does, then why should they support it?

I assume it is not simply a matter of converting the package from RPM
with alien, or manually extracting things and hack them together to
get a working binary? No, it should not be necessary, but it is
something to use against them when asking why they don't support one of
the biggest distributions out there. If they already have code that
runs on Linux it shouldn't be that big of a deal to run on multiple
distributions. _Supporting_ all of them is another deal entirely.

Another thing you could try, is to see if Canonical will back you. They
may have some clout to get the manufacturer to provide a .deb, and this
sounds like the sort of hardware they would want to see supported. Yes,
they will probably ask for a package for Ubuntu, but it will get you a
lot closer than where you are now. They might even be willing to ask
for a package that also runs on pure Debian, as it shouldn't be too
much effort to make sure it runs on both. I know that Canonical has
worked with vendors in the past to get them to support their
distribution, so it shouldn't be a new problem to them.
