I could compile and get the c64x.ko. But the real problem is there's no c64x_drv.bin(DSP firmware ?). When c64x.ko is loaded into kernel space, it try to open a c64x_drv.bin and stop being loaded. Look DirectFB/gfxdrivers/davinci/kernel-module/c64x/c64x.c. I couldn't find source codes or a binary for a c64x_drv.bin anywhere.
