I was also able to get it working in serial mode, but I also have a question.

I followed the instructions I searched for and everything worked out fine except the last step. I want to install the desktop shortcut, but that script won't work - I get a "Permission Denied" message. This is running from xterm and executing sudo gainroot.

Now that I think about it I have another question... if I screw up (again) and don't rerun the btkbd script to disconnect the keyboard properly, how do I get the on screen keyboard back without the dreaded "Restore original settings"? There must be a better way.
