I'm trying to add support for Settings for the original VX-8R. I just recently have been switching over to chirp for all of my radios and was surprised to find that the Settings tab was empty after downloading from my VX-8R. After a few modifications to the vx8.py driver, I have settings coming up properly for my radio but have doubtless broken support for the VX-8DR. 

The VX8-DR has expanded APRS features such as SmartBeaconing, more Message Macros, more DigiPaths, etc. These affect the memory layout some. To fix it (temporarily), I corrected the memory layout to align with the VX-8R and commented out the calls that referenced the now missing memory elements. 

I'd like to contribute the changes back but I'm not sure how to handle support for both the VX-8R and VX-8DR (and VX-8GER). With differences in memory layout, should the VX-8R have a separate driver or can the memory layout differences be somehow accommodated within the same driver?

73's,
