- split driver into FreeBSD specific and camera specific portions (qcamio.c can run in user mode, with a Linux "driver top" etc, and qcam.c should be trivial to port to NetBSD and BSDI.) - support for 4bppand bidirectional transfers working better - start of interleaved data-transfers byte-stream decodes (some of this stuff has been pulled out for the moment to make it easier to debug) At this point, anyone who wants to port it to other platforms should feel free to do so. Please feed changes directly back to me so that I can produce a unified distribution.
