Sounds like you are in a jam. As far as I understand it, given the current syllabus, either you have to lower your hiring standards or do the work yourself. I've done both of those things in the past, and it was always a pain. Ultimately I settled for reducing the amount of TA work that had to be done. A lot of grading is probably optional, you might not be required to have a midterm and final, stuff like that. Rather than let yourself be victimized here, try to be creative with the resources that you do have, you'll figure something out.
Foobar -- that's a great plan, and let me assure you there is a lot of activity going on in the background.
If you want to talk about this, and you're on the Berkeley campus, I sit in Soda Hall 739. Alternatively, I hike most evenings in Tilden Park for exercise -- if you'd like to join me sometime and talk about your ideas, I'd certainly welcome hearing them.
Oh, I'm not in your class or even at Berkeley. I'm just discussing things on an internet forum. Good luck though, because from the comments here it sounds like your students are pretty angry, and admin is being unhelpful.
