What error are you getting while building SGX modules for 2.6.34? SGX modules have nothing to do with the creation/deletion of /dev/fbx nodes AFAIK. > If I build the kernel from scratch, you knonw, I cannot make the omapfb work > properly > I still doubt whether the FB/DSS support is enabled in your kernel config or not. Have you enabled VRAM and what about CONFIG_FB_OMAP2_NUM_FBS?
