Well, I couldn't reproduce it reliably. One out of 4-5 reboots exhibited this 
behavior. Unfortunately, the webcam acquired for this machine, did not have a 
FreeBSD driver (it was going to be used for shop surveillance), so it's 
furnished with Windows now. I may rip out the card and put it in a Dell that 
currently uses bge cards, but that won't be soon.
