For some time I used a notebook, which was equipped with an M4 mobile graphics chipset. Unfortunately the framebuffer driver of Linux refused to work with it. Instead, funny color shapes appeared on the screen every time the notebook booted. Knowing that the XFree86 driver worked, I started to compare both drivers. It turned out that the driver included in Linux 2.4 didn’t have support for flat panels at all. So, with kind help from Andi, who wanted to use it on his Mac and who is an experienced DirectFB developer, I wrote this new framebuffer driver for Linux 2.4. Be warned, it has probably never been tested on something different than M3 and M4 chipsets using flat panels.
