Euh, well, i think the X / OpenGL approach showed us that to do DMA/IRQ, you need a kernel module, and what X/OpenGL is the DRI thingy. Would it make sense for directfb to re-use this selfsame infrasturcture, which already exists in the kernel, and is used by X, so kind of guaranteed to be available for many graphic cards ? But maybe it is too complex or something ?
