Subject: 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)
