After my last query to this list, I fixed up my semaphore modifications for motion 2.6.2 a bit and now I can reliably get two cameras to work capturing continuously on the same machine for several weeks without problems.
I have placed my hacked up versions of motion 2.6.2 at: http://www.interstice.com/drewes/motion-2.6.2-with-semaphore.tgz My modifications have been noted in the code with my initials, "RPD". Please note that this code is a bit hacky and should probably be cleaned up in several ways. For example, you must start the motion process for /dev/video0 *first* since only the motion process on /dev/video0 will attempt to initialize the SYSV semaphores. If you start /dev/video1 first, the semaphores will not exist and things won't work. In your startup script, pause for 5 seconds or so between the startup of the motion process on /dev/video before you attempt to start the other video devices. Sorry I don't have time right now to prepare patches, but at the current state of the code it isn't ready for mainstream use anyway.
