Let's summarize the current situation:

1) Hardware vendors don't have to tell us how to program their products,
as long as they provide some way to use it (i.e. binary blob driver).

2) Hardware vendors don't want to tell us how to program their products,
because they think this information is their secret sauce (or maybe
their competitor's secret sauce).

3) Hardware vendors don't tell us how to program their products, because
they know about (1) and they believe (2).



4) We need products with datasheets because of our development model.

5) We want products with capabilities that these vendors advertise.

6) Products that satisfy both (4) and (5) are often scarce or
non-existent.


So far, the suggestions I've seen to resolve the above conflict fall
into three categories:

a) Force vendors to provide datasheets. 

b) Entice vendors to provide datasheets.

c) Reverse engineer the hardware and write our own datasheets.

Solution (a) involves denial of point (1), mostly through the use of
analogy and allegory. Alternatively, one can try to change the law
through government channels.

Solution (b) requires market pressure, charity, or visionary management.
We can't exert enough market pressure currently to make much difference.
Charity sometimes gives us datasheets for old hardware. Visionary
management is the future.

Solution (c) is what we do now, with varying degrees of success. A good
example is the R300 support in the radeon DRM module.

Did I miss anything?
