Did anything you try effect the frequency of the hangs?
If you quicksave and quickload can you go another 4 or 5 loading screens? Exiting and restarting would presumably reset the count, at least.
Unfortunately, even if it wasn't inconvenient to use the Developer Mode teleport functions frequently, there are some story and quest events triggered when entering or leaving certain areas (such as entering the Black Boar tavern the first time), which you would miss doing that.
