Let me know if I can help test the driver fixes. The combination of real mount and ccd simulator works really well for that purpose.
On a separate note: Have you considered making this into a generic telescope driver / mount model that just talks to the motor controller on arbitrary telescopes? Or pull the functionality into a separate mount mode / telescope pointing plugin that can be used by telescope drivers? I started reading about the different approaches to aligning and calculating pointing models and I think it would be great if these research papers could be put into practice easily.
