The problem is not with just screen mapping for drawing something(open 
screen memory for drawing is simple just mmap some part of /dev/mem & viola ...)
My problem is that i am unabl to properly map some shadow screen for 0xA0000-0xB0000 address.... It's highly needable for programs working with screen background..
 I hope the libdtk will help me..
