With Patrick's diff, my amd64 Macbook2,1 has video0 at uvideo0 again.
I compiled the patched kernel with UVIDEO_DEBUG, dmesg below. Thanks!

video(1) still doesn't work though: running 'video -v'
opens a black window of nothing, saying

The ioctl error message is after I pressed 'q' to quit.

These are the UVIDEO_DEBUG messages when running that:
