Yeah, I hate to tell you, but I'd say your motherboard is toast.
Not only is the circuit board physically broken off, you've got some burnt components right next to it. That's not to say it's impossible to fix, but honestly it's beyond the capabilities of most average DIY-ers; this is going to take expertise in circuit board repair and troubleshooting, as well as boardview files and schematic diagrams.
Personally I'd be looking for a replacement motherboard if I were you, otherwise you're going to have to find a very good repair shop. I consider myself above average with regard to electronics repairs and I'd say this one's beyond me.
