Yes, there's a project on projects.openmoko.org too (with a mailing-list and

Last time I tried, I think it was working with the following values:
390 38240 -4332684 -51177 -123 47146512 65536

I had this problem the first time, the fix was a little patch, now available
on the gentoo at openmoko overlay:
I think that the driver is not telling that EV_SYN is available in its
so tslib doesn't recognize EV_SYN events (EV_SYN is event type 0 according to
A better fix would be check why it is done this way and do this right in the
driver (maybe my analysis is wrong too, it needs to be checked).
It may be interesting to see how this is done in other distributions too.
And there's a patch in mokomakefiles called tslib-input_raw-grab_events.patch
that may be interesting to use too.
