I haven't seen you complain about stability before, just about rotation and mic volume. What stability issues are you having?
And yes, I'm rather busy. I understand that rotation and mic volume are annoyances, and I do occasionally look into them and release test fixes. But this is pretty much stabbing in the dark, as I don't own the device.
Speaking of fixes, the new unified kernel and multi-rom work has gotten me back into working on thunderc a bit. If anyone wants to try the multi-rom that I made last week and report on the results, that would be a big help:

This one zip file should install on all thunderc models (VM670, LS670, VS660). It detects the model at install time and copies the appropriate files.
