[samsung-i9070] Add framebuffer mode in initfs-hook
After various tests we finally discovered that the framebuffer mode have to be set otherwise the osk-sdl
initialized the framebuffer with a wrong memory size and doesn't work.
Even the order of the framebuffer settings matters, if the cat ..modes > ..mode
is placed before the bits_per_pixel
and the virtual_size
, it doesn't work correctly.
(Here a small utility used to do the investigations)
