CPU intensive touch-pad on the OpenMoko

it seems that using the touchpad causes alot of cpu usage. I have an
which reports mouse movement events to a function. So I have this area
where I can press and drag around the pointer with the stylus. Whenever I do
that the CPU %sy utilization in top goes up to 50%-60%.. Shouldn't we be
able to expect that we get more time for userspace than for the kernel
if we just move the pointer around? 50-60% seems extremely absurd...
PS if you want to test what I mean, download and install my application
