You can mmap() the frame buffer, but have a look at the ten thousands lines of code in the XFree86 Xserver that deal with every and each hardware idiosyncrasy of the various not-really-compatible graphics cards. I'm sure, you'll immediately give up your idea. Your best bet by the time the next release of XFree86/tm will be out is to use their ``DGA'' (direct graphics access ?)
