I have an macbook 5,1 2009 and my iSight camera hadn’t worked since Sierra so I know how you feel but happy you got you MacBook up and runningPatch Updater launched itself about 20 minutes ago, and displayed the latest patches for Siri and iSight, so I installed them (Mid 2009 Macbook 5,2). Siri now works fine (thank you!), but my iSight camera still doesn't work (Photo Booth doesn't see it), but from what I understand, it may not be possible to get the iSight camera on this model to work.
