Okay, I'm kicking this thread, because I have the answer (well, ish, at least) and some other person might use this information.
The Trust 1200 tablet I own (well, I own a Medion actually, which I found to be a clone of the Trust device) is a clone of the Aiptek 12000U. The Medion thus is either a clone of a clone or just a clone :P
Linux kernels 2.4 and 2.5 (and therefore 2.6 later this year) have built in support for this tablet. Some guy at sourceforge made a driver for XFree 4.2.1 for it and submitted the driver to XFree. I have contacted both the XFree devvers and the author of the driver, and it is supposed to be included in an upcoming release of X.
And when that's done, the tablets will work.

Nice
