That would be nice, however I'm not much of a kernel hacker (Linux or OpenBSD) so I wouldn't be much help. > My impression (and I could be wrong) was that some of the purpose of the blob was to > maintain a common internal protocol layer on all (x86) platforms that the "driver" just > linked to and knew would work.
