After further investigation, this indeed seems to be a problem at the driver/android/somewhere level...

The device capabilities:

                 (('ABS_MT_POSITION_X', 53),
                  AbsInfo(value=0, min=0, max=1536, fuzz=0, flat=0, resolution=0)),

So min=0, max=1536.

On a working device, if I touch the far left:
> absolute axis event at 6366.763794, ABS_MT_POSITION_X event at 6366.763794, code 53, type 03, val 00

And on the far right:
> absolute axis event at 6371.031397, ABS_MT_POSITION_X event at 6371.031397, code 53, type 03, val 1535

In a broken state:
> absolute axis event at 6705.620880, ABS_MT_POSITION_X event at 6705.620880, code 53, type 03, val 91
> absolute axis event at 6707.924863, ABS_MT_POSITION_X event at 6707.924863, code 53, type 03, val 1453

So... something goes into a state where the input "area" grows out of the device... The whole physical area is still active, but the delivered events are "closer" to the center of the device.
