The touchscreen driver s3c2410_ts.c doesn't work well when using
the tslib, an abstraction layer for touchscreen panel events.
Tslib needs ABS_X ABS_Y and ABS_PRESSURE events to report, but only
the former two the driver can provide.

It seems much more sane to fix this in tslib, the kernel is not actually
reporting pressure meaningfully here and there's already BTN_TOUCH to
report if the pen is down.

yeah,I will try to fix it in tslib.

You may send a patch to tslib. 

Thanks a lot.
