Well I did just find something interesting in an old article, in case someone else is on this quest...
The M220 was standard with XP, but Linux was a factory option! L@@K HERE!
I also found the M220 is still supported on the company website, but can not find any support for Linux there.
They even still had the User's Manual, here
I found the Linux TouchScreen Driver
Well, that's all for now!
