using fb1

hi,
I am starting to work with SM712 driver which was in drivers/staging, but then removed. I have a demoboard of SM712, and testing the existing code on it.
After the module is inserted the board is initialized, and /dev/fb1 is successfully created. But after that how do i test? how do i confugure ubuntu to use that /dev/fb1 ?
I know it is not the proper place to post this, and I should have posted in some ubuntu specific forum or list, but i thought this will be the best place to get the best answer.
Looking forward for some pointer or some idea / hints in this regard.

thanks
sudip
