Hello all,

First the status :
* The fbd has been ported and it's attaching with the fb0 devie. There's
   an fb0 device entry created.
* In the following commit I have added mmap to libbsd. This works like a
wrapper to the mmap in cpukit :

Blocker :
* After the fb0 is created and mmap is added, I don't see anything on
  the screen. From the FreeBSD, it seemed like the VT driver is needed
and that is responsible for turning on the screen. So I have ported a
minimal version of the VT with only the initialization and allocate parts:

But even after porting the VT driver which initializes well ( As the
message during booting says). I don't see anything on the screen.
I need some ideas on what is missing or how to debug this.

The app I'm using to test framebuffer is pushed here :

Any idea regarding this is greatly appreciated.
