Looks like my thread has been hijacked LOL. But nevermind, it's all good info. Too busy with work, and I'm too lazy to check the forums...
I think the point of having fuse today is not preventing the IC from smoking, but the house from smoking.

I got my board fabbed and soldered, a few minor bugs (mostly placement) but so far it's working.
It runs too hot (like I can't stick my finger to the backside of the PCB) if the stepper is set to run at 1.5A. I am getting some heatsink for that.
The HBP can handles 10A well though - large enough copper pour for the heatsink.
Currently I am working on writing a new firmware. I am porting ChibiOS/RT to Due (SAM3XA specifically) and writing firmware on top of it.
I get some basic working - Eclipse compilation. Drivers like USB, ADC, PWM, and Dual CDC over USB. (OS port: [github.com])
But at this speed, I guess it will take months for a firmware that achieve Marlin parity features.
PM me if someone want to join the development =)
