Mine show 

X:  0.09
Z: -1.02
Y:  0.09

which translates to all applications using the accelerometers to 
consider the unit to be slightly tilted when it's lying flat an the 
surface of a table. (And yes, the table is not tilted. ;)

On the contrary, I need to tilt the unit to let X and Y become zero ar 
to center XEyes' pupils.

A friend's N900 shows the XEyes' pupils as expected, ie. centered while 
the device lies on its back. I do not know this device's raw values, 
however.

According to a mail from Nokia I got today, there's no way to 
recalibrate the sensors...

What accDisplay-readings do other units produce? Maybe some other N900 
owners could post their values?
