You could do it that way. You might want to look at the dri project (http://dri.sf.net) though. That way you can get an idea of how X talks to the kernel driver and such as well as make your driver consistant with the rest of the open source drivers out there. You can also use the DRI code from another driver, perhaps the r200, as a basis for your driver. Also as I recall the r128 driver supported DMA based Xvideo (overlay), so if you are looking to do that in your driver the r128 driver would be a good starting point.
