Part of the issue, at least in the ATI-nVidia world, is that the hardware
itself infringes on some patents and releasing docs and/or source code (for
that part of the chip) would advertise to the patent holder that there was
infringement. I don't think that this is the case with Intel, however,
because they release open source drivers that are planned to be fully
functional (minus some patented texture compression and some other minor
details, I think) that they make no attempt to obfuscate.
