The driver now compiles correctly without any x headers or libraries installed
The bitmap and stroke code can't be shared with glx anymore because of this. The model for the mini teapot is restored and I have tested it to work with linux-fbdev and linux-solo The driver recognizes 32bpp where there is no alpha (my radeon 7500) It also sets the correct number of cmap entrees (instead of 256 which can be an error)
