Somebody in the thread at some point said:

| In mach-gta02 we have:
|
| .presc = 0xff, /* slow as we can go */
|
| We can also have:
|
| .presc_first_points = 0x10,  /* go faster before the first N points
| are reported */
| .prest_first_points_n = 2;
|
| From what I see in the manual of the CPU the absolute minimum value
| that should be used here (presc_first_points) is 0x05. Right? I guess
| that in practice 0x10 is small enough to be considered a minimum for
| the initial tests.

Sounds good.

But in the meanwhile I noticed this thread on community list

http://lists.openmoko.org/pipermail/community/2009-January/040823.html

I would satisfy yourself that there is a genuine problem on touchscreen
side first.
