This might not be right, many vendors don't want their competitors to know their interface specification (to prevent cheap clones). FreeBSD does not have that restriction, so you may have it backwards. >I've also written skeleton drivers for hardware vendors; typically they >just have to fill in the very lowest level of the driver for their device, >the rest can be generated in a couple of hours based on only the very >simplest description.

A better solution is to lower the barrier to entry so that people (including hardware vendors) can supply drivers. Right now the situation is that both sides say "Documentation is not in our best interest, so you cannot have any.", which is bad. Actually such a document COULD INCREASE DEVICE SUPPORT which is a MAJOR FACTOR in people's decision to use or avoid an OS. Perhaps less time could be spent whining about lack of users and how users don't have clue and more time could be spent making the good technology accessible.
