Yes, a two-phase bootstrap is a little tricky and I have done it only once
for the Letux 400 some years ago.

The squeeze image did use the tslib and ts_calibrate, but the X11
input driver is missing on Wheezy. And taking it from Ubuntu or
Unstable is broken (X-server segfaults).

Please take a look here, it has the right pointers:


This script can be run on the GTA04 to install useful things, incl.
xinput-calibrator (from Ubuntu).
